    Really pissed off with @O2 .. Really what sort of network can't give someone mobile data even at 25mins past midnight, "oh your area is busy" or "oh there's mast issues" same **** different day for months, how about you upgrade your hardware if its so bloody busy! USELESS! #O2

    That’s the last time I recommend @O2 to anyone. Appalling service and indifferent customer service. What has happened to a once great provider?

  • meljodmor11 Mm♡ (@meljodmor11) reported

    Awaiting a phone call from @O2 after being misinformed (in great depth) by one of your customer support team. Can somebody tell when that’s likely to be, please????

  • LauraJoyChapman Laura Chapman (@LauraJoyChapman) reported

    @O2 I’ve messaged you. Hoping you can help. Otherwise we are switching to @VodafoneUK as they tell there customers when they could be charged or being charged! #alotofmoney
