Amazing customer service by Claudia
Whilst trying to get my pac code I had experienced multiple brick walls in being able to get it sent to me so eventually went in store as the customer service over the phone were unable to assist me.
I was thankfully greeted by Claudia who went above and beyond to ensure I was not messed around any further than I had already been. She spent almost an hour calling the call centre multiple times, trying to get the correct assistance to be able to get a pac code sent to me due to the error that had initially occurred from o2 cancelling my service and number 5 days before got some unknown reason.
She was absolutely amazing and a huge credit to o2, if only all the staff were as thorough and helpful as she was … if so, I wouldn’t have needed to leave o2 after many many years of being loyal in the first place
Thank you Claudia, anyone else would have given up long before you did and I would have been forced to loose my number on top of everything else!

After an awful online experience
After an awful online experience with the O2 customer service team this morning (tel no. 202) whereby they rendered my mobile useless by killing the sim before the new sim was delivered, Claudio saved my day by calmly replacing the sim and making a call to get it activated. I have no confidence in the 202 service and will always go to the store in future. Thank you again Claudio

Hi Bart, thanks for the review. We're sorry to hear about the experience you had with the online customer service team and the inconvenience caused during your SIM replacement. However, we're delighted that Claudio was able to turn things around for you. His calm approach, expertise, and determination to get your new SIM activated and your service back up and running are exactly the kind of support we strive to provide.
We'll be sure to pass on your kind words to Claudio, who will be thrilled to know he made such a positive difference.
DANIEL FROM O2 CUSTOMER CARE…
IT WOULD BE 5* IF HE WAS ALLOWED TO DO HIS JOB CORRECTLY. DANIEL FROM O2 CUSTOMER CARE DEPARTMENT BRILLIANT ASK FOR HIM.
WHEN YOU PUT IN A COMPLAINT ASK FOR THE REFERENCE NUMBER STRAIGHT AWAY. IF THEY CANNOT GIVE YOU ONE NO COMPLAINT HAS BEEN PLACED.
BEFORE YOU CALL O2 GET THE INFORMATION FROM THE ONLINE PORTAL REGARDING YOUR COMPLAINT.
IF YOU FIND THAT YOU ARE BEING IGNORED READ IT OUT TO THE PERSON. IT IS 90% POSSIBLE THAT THE MANAGER WILL GIVE THE PERSON FALSE DETAILS TO GIVE YOU.
READ IT AGAIN AND STATE THE REFERENCE NAME AND COMPANY SITE ASKING THEM TO LOG INTO IT THRMSELVES .
ALMOST 2 HOURS HES BEEN TRYING TO SORT EVERYTHING OUT AND CONFIRMED WHAT I WAS SAYING WAS CORRECT NOT HIS MANAGER.

Loyal Customer Let Down by Poor Service and Unexpected Charges
I am extremely disappointed with my experience with O2 after being a loyal customer for several years.
Over time, the network service in my area deteriorated significantly, causing me considerable inconvenience. There were numerous occasions when people were unable to reach me during urgent business and personal matters. I raised this issue with O2 multiple times over an extended period, but unfortunately, the problem was never resolved.
As a result, I decided to switch to another provider. I contacted O2 beforehand and was assured that porting my number would not be a problem. The port was processed successfully, and I even received a refund from O2. However, I was later surprised to receive a bill for £258, which O2 stated was an early termination charge.
When I contacted customer services to query this, I was even more disappointed to learn that previous conversations—including several calls made by both my wife and me regarding this matter—could not be found because they had apparently not been recorded on their system. This made it extremely difficult to resolve the dispute.
Based on my experience, I have lost confidence in O2’s customer service and complaint-handling process. I regret choosing O2 and would not personally recommend their services. If you are considering joining O2, I would encourage you to carefully review the terms of your contract and keep your own records of any conversations with customer support.

Hi Desmond, thank you for taking the time to leave a review and for your comments.
We're sorry to hear that your experience has left you feeling disappointed, particularly after being a loyal customer for several years.
We understand how frustrating it must have been to experience ongoing network issues and feel that the impact on both your personal and business communications was not resolved despite raising your concerns on multiple occasions. Reliable service is something our customers rightly expect, so we're sorry to hear that this was not your experience.
We're also disappointed to learn of the difficulties you encountered during the process of leaving O2, including the concerns you've raised regarding the charges applied to your account and the information available from previous conversations.
We would love to be able to put things right for you, so if you do still need us to look into your account please to reach out to our teams on social media and they will be more than happy to help.

Helpful & efficient
Claudia & Harry were so helpful and efficient changing our pay as you go sim plan to an eSIM with a contract, saving us money along the way and giving us a better deal. Claudia also transferred all our info from our old phones to the new ones even though we had not purchased the phones from them.
We received great customer service and definitely recommend them.
