    @O2 Number ported in to O2 yesterday. Supposed to have completed by 6pm. Customer services said wait until 8pm. Still no service despite rebooting many times and old sim has lost service.

  • s9pke Handy Hunks (@s9pke) reported

    @O2 by far and cannot emphasise enough how poor o2 have gone. 1 month of calling, no responses. No complaints logged for me, still charging me and no help. Hours wasted and money and time. There must be a way to escalate @ofgem

    @O2 the signal in GL9 1DF is shocking, thought you were putting up a temporary mast at @bhorsetrials?!

  • urvijablahblah Urvijaa (@urvijablahblah) reported

    @O2 terrible service - sim not working on day 3 itself, despite full recharge. Can't reach customer care also. Pl help!

  • GreyWolfDesignz AJ 🇬🇧 🇩🇪 (@GreyWolfDesignz) reported

    @O2 Evening all, are you having network problems with 5G tonight at all? Can't seem to get 5G anywhere on my 5G enabled phone and checker doesn't seem to show any issues :/

    @O2 why had O2 changed, meaning g your customer service is bad as Virgin, called 3 times to get Refund in last 2 months and every time your staff have lied to me, today I ring up and it’s the sam excuses, honestly it’s is so disrespectful, staff don’t listen or tell you the truth

  • BobPlumb7 **** Burger,🏴󠁧󠁢󠁥󠁮󠁧󠁿🇺🇲 100% #BackBoris (@BobPlumb7) reported

    @O2 1st operator said go to store 0 help, 2nd operator never noticed my acct was not active so the number swap the operator arranged got cancelled, 3rd operator sorted my acct but not transfer of old number from 3, total time spent on 3 calls and 1 shop visit = maybe 5-6 hrs

  • benb3n_ ben (@benb3n_) reported

    @O2 how long should I expect to be offline when porting my number to you? Got a message that it would be done today, both the old and new sim are not getting any service. I’ve rebooted the phone several times
