Lord Shaun O’Brien 🇺🇦 (@lordshaun_) reported from London Colney, EnglandThe customer service of @O2 is truly one of the worst I’ve ever come across.

Been on the chat thing for four hrs

Ben (@behu91) reported from Hemel Hempstead, England@O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England@O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

Rebecca Ashcroft (@Ash42055) reported@O2 I can’t believe I have spent over 2 hours in the last 3 days to customer service team to sort out my airtime plan for my new watch which was cancelled by an advisor by accident on Tuesday.
