What went wrong you ask? I think the correct question is what didn’t go wrong. I have been a customer of o2 for several years, and they successfully disappoint every single time. My worst experiences have always been with o2’s customer service. My dog could have solved my issues compared to the jobworths over the phone. I informed o2 I was moving abroad on several occasions, but apparently there is extreme difficulty in understanding that. 02 definitely teaches you that common sense is not so common and that bare minimum intelligence is not a flower which grows in every garden. A certain individual over the phone informed me the “only way” to cancel my UK phone number was to return to the UK and visit a UK store. As you can imagine, I thought it was sarcasm. After many phone calls I eventually managed to cancel my UK number and I am now with a different provider who actually has employees which have common sense.
