Got eventually there. On trying 150 online a recorded message just says not enough credit to make the call. Need to top up but does not advise how. Waste of digital effort.

On-line top-up worked reasonably well, but my 1st attempt failed miserably and I needed to get assistance from EE (top-up) help line, but in the end, they sorted it out for me.

About On Top Up
Written by the company
On Top Up provides an easy way to purchase topup vouchers and credit for Pay As You Go mobile phones. We cover all the major phone networks, allowing users to add multiple phones on different networks to their account, and topup whenever they need.
Please note, that any accounts that opt-in to Auto Topup will have their subscription renewed automatically each month, and for security purposes you will need to log into your account in order to apply the credit to your mobile phone.
Our optional Auto Topup service allows users to automatically buy a topup every month, to help ensure they never run out of credit on their phone(s). The Auto Topup service can be started and paused or cancelled at any time simply by clicking a button in the user account area.

Total Scam
Total Scam. I bought a one off top-up in an emergency in January, had to ring them and ask for my voucher, as I had not received anything, when I tried to put it on the phone it said voucher was already used! fast forward one month and they email me a receipt for my purchase, another top-up! Tried to sign in to my 'account' and email was not recognised. Rang them up and they said I had subscribed......oh no I didn't! Now have an email to say my account is closed, let's see if my money is returned............

I topped up once through Lebara by mistake
I topped up once through Lebara, I didn't know it was another company. It was a mistake,I didn't need extra and Lebara refunded me. I did not enter into anything, and as Lebara had refunded it I did not know that they would be taking money off me every month. I have blocked them from my bank . They claim I have vouchers on my Lebara account, there are none. I have tried to cancel it all and they refuse to do this. I will see where else I can warn people. Please don't use these people. My bank First Direct , said they have a lot of problems with these people. So be aware, they might try to take other amounts off you

It was a great solution using this…
It was a great solution using this route to top up my Tesco line as I am currently in Nigeria. It saves my Tesco line from disconnection

Disagusted…
I an well into my 80s not particularly tech.savvy and have just bought a pay as you go phone for the first time, and decided to use" on top up " for a first top up.What a huge mistake. I was not aware nor, told that this was a contract and in a months time I would be billed again for a similar amount. Fuming I decided to rase this with them to no avail, so I cancelled
this contract. which has cost me some more money This I can do without . I feel that this company is a scam and people should boycott it. For the sum of some £28 it is not financially worth going to the small claims courts to plead my case. I feel betrayed and disgusted by this so called company,and I shall think twice before this can happen again.
