I recently switched from Sky broadband to 3 mobile broadband with its outdoor router and alleged 5G coverage.

However, despite these misleading claims there is no 5G coverage and my Wi-Fi coverage throughout my house is terrible.

Even worse however is Three’s broadband customer service which entails spending hours on the phone and getting absolute nowhere.

I’ve now resorted to initiating a formal complaint and repeatedly receive emails from Three asking me for my account details which I’ve given them many times already.

I am more than happy to amend this review as and when Three finally respond to my formal complaint. Until then, it shall remain visible for all to see for those thinking of switching their broadband to this provider

Two days with Three was enough

I joined Three on Saturday for a very simple reason: I wanted to test a mobile data connection for a technical project. I expected it to take perhaps half an hour. Instead, I have wasted around five hours, driven 30 minutes to a Three store, spoken to numerous advisers, been hung up on, had an unexplained charge taken from my account, and still ended up with a SIM that does not work properly.

I initially bought a data plan online, then bought a Three PAYG SIM from Asda because I wanted to get everything working that day. I assumed I could use that SIM with the plan I had purchased.

After around 15–20 minutes on the phone, Three eventually explained that I couldn't and that I needed the specific SIM linked to the online order.

So I drove to a Three store to collect it. They refused to give it to me because my ID was on my phone rather than the original physical document.

The staff member suggested I cancel that account and use the PAYG SIM instead. He then claimed my phone was faulty because the SIM wasn't showing a number. When he put the SIM into his own tablet, the number didn't show there either. Shortly afterwards, the SIM finally activated and Three texted me the number.

Back home, I called Three again and asked them to cancel the original account. I was told it was cancelled and that my £10 refund could take 28 days.

I then topped up the PAYG SIM with another £10. It showed as active, but I still couldn't access the internet properly or make outgoing calls.

I was promised a callback the following day. On Sunday morning my phone rang once and stopped. Calling the number back produced a Three recording saying they had tried to contact me.

I then discovered a third £10 charge on my account which I had not knowingly authorised.

On Monday I called again. The first adviser denied Three had called me back and resisted escalating my complaint, despite me explaining the unexplained charge, poor customer service, bad store advice and the fact the SIM still didn't work. He eventually hung up on me. I had not sworn at him or abused him.

I called back and another adviser, who was actually very pleasant, transferred me to complaints.

The complaints adviser asked me to obtain the transaction ID for the unexplained charge from my bank. I did exactly that, confirmed it several times with the bank, and the bank confirmed the charge came from Three.

When Three called me back, the adviser simply said it wasn't a transaction ID and refused to investigate it further. After considerable back and forth, her answer was essentially that if I was unhappy, I could go to the Ombudsman.

At that point I gave up.

Something that should have taken half an hour turned into roughly five hours of wasted time, petrol, contradictory advice, poor support, an unexplained charge and a SIM that still does not work properly.

I have now asked Three to close everything.

I had heard for years that Three had a reputation for poor customer service. After being a customer for barely two days, I understand why.

One star only because zero isn't an option.
