    @O2 Hi, yeah have good signal. Can you check please if the correct number was ported over

  • naiadzhara Claire Boydell (@naiadzhara) reported

    @O2 - I’ve been with O2 for 16 years. I now truly regret this and will be leaving O2 as soon as I possibly can. Please - if you’re reading this & are unsure whether to join O2 …don’t. Really don’t. The customer service is so far past awful I don’t know what word to use for it.

  • chrisbolton Chris Bolton (@chrisbolton) reported

    How come @O2 don’t offer telephone or chat support anymore? There is literally no way to get hold of them now.

  • naiadzhara Claire Boydell (@naiadzhara) reported

    @O2 I’ve never done this with a company before but I’m going to tell everyone I know, on every platform I have, to avoid O2. I couldn’t make up the saga of the last month, last 30 or so calls, last 12-15 hours of my time wasted on the phone with O2, if I tried.

  • JasonRooney10 Sir Grandad Roons (@JasonRooney10) reported

    @O2 why can't I speak with anyone on the phone anymore. I need to set up a direct debit, pay a bill & the phone keeps going dead or people are putting the phone down. Looks like I maybe going somewhere else now

  • Henry_Keating87 Henry Keating (@Henry_Keating87) reported

    @O2 attempt 6 to fix the local mast to day …. Fingers crossed …. Again

  • TracyWoods69 Tracy Woods (@TracyWoods69) reported

    @O2 as a new customer, is the My O2 app ever up and running properly. After eventually managing to activate it this morning the app is “being worked on” as an error message!!

  • MASUK2020 Tubthumper (@MASUK2020) reported

    @O2 Already tried all.of these steps. My partner's phone is on O2 too and she has the same issues.

  • RedPandaNiz Niz 🔜 CFz! (@RedPandaNiz) reported

    @JymFox @ThreeUK I left them for the exact same reason and went to @O2 instead as they are the only ones not reintroducing roaming charges and I fully support that decision 👍

  • JonRouse9 Jon Rouse (@JonRouse9) reported

    @O2 After seven calls in which your own staff couldn’t sort the issue out, you have the audacity to refer me to a self help guide.🤬
