    @O2 Day 7 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.

    @O2 I have lost my sim in Morocco! How can I cancel ASAP please

  • DaveHowes84 Dave Howes (@DaveHowes84) reported

    @O2 I apologise, it was Friday, that's my bad but it's still a long time to wait for a reply to a DM. If they hadn't told me on 202 that they couldn't find my account that I clearly have I could of had this all wrapped up in about 5 minutes.

    Hi @O2 we’ve been in Blackpool most of the day and have little or no signal until we were leaving. Do you have a known issue, a lack of cell towers or something? We’ve been half a dozen times this year and it’s always the same on 3 different phones.

    @O2 can u help me pls,, my contract is almost up and I’m wondering whether I can switch to a different sim plan rather than upgrade my current one

  • KatWolseley Kat Wolseley (@KatWolseley) reported

    @O2 I have just encountered the most unhelpful staff called James at the Leamington Spa branch today. I walked in at 15.45 wanting help with my Pac Code and he just doesn't want to know, spent 10 mins arguing why he can't help because he has a train to catch at 1600.

  • george_i81 George Ivanov (@george_i81) reported

    @O2 I spent 3 hours in @fdarena without a working internet connection! Is the signal supposed to be this bad indoor in Leeds?!

  • notdodgy Roger Leitch (@notdodgy) reported from Solihull, England

    @O2 9 hours after you reported it fixed (again). O2 Network Update: Stratford Rd, Shirley, Solihull B90 4AJ, UK Looks like a nearby phone mast isn’t working as it should, sorry.

  • SR_ARUN_ SR (@SR_ARUN_) reported

    @O2 ***** Service. While on call disconnecting the call without any information. 5 days without signal in O2 E SIM. What the hell u are doing!??????

  • jayjays1986 Jen Deburgh (@jayjays1986) reported

    @O2 She's tried emailing yourselves but has got nowhere, @DHLParcelUK have been no help and have said to make a claim with you despite their driving giving the parcel to a random person outside our house. #watchdog #ombudsman
