    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @O2 please can you sort out the signal in B37, its been going on for months now. I've tried using WiFi calling (I'm with virgin media as part of my plan) doesn't really work. I keep missing important calls and messages.

  • DevaConUK DevaCon (@DevaConUK) reported

    @O2 I'm trying to contact Collections but all calls don't get through. I am receiving no texts from anywhere including govt sources and security checks. What is your customer service number? I'm in Chester where you have little signal.

    @O2 Don't buy from 02 they sell shoddy goods and will take no responsibility and they leave the customer holding the bag!

  • duceydan Danny Duce (@duceydan) reported

    @O2 Not had a response and my order is missing due to your error. Poor customer service to resolve this so far so please get back to me and sort this out

  • DomMog86 T (@DomMog86) reported

    @O2 Hi, my nearly 6 month old S22 keeps dropping signal during calls resulting in robotic voice, stuttering, long silent periods during a call. This has been happening for a while. Any suggestions on how to fix this? Thanks.

  • lookitskris Kris 🦣: @lookitskris@hachyderm.io (@lookitskris) reported

    @CraigHawker @O2 I'm giving @SMARTYMobileUK a go. No contract and roaming included. Uses the Three network (who I was with before) and its working just the same

  • LyannaReed Lyanna Reed (@LyannaReed) reported

    @O2 No network coverage again today.. this happens every other day these days with no message to inform of issues. Never any apology/discount and you expect us to pay our bill every month. Had enough!

  • Lava087 Simon (@Lava087) reported

    @O2 how long does it take to cancel my account from my previous provider with a STAC? I gave you my STAC last Wednesday… My old number is still connected to my old provider…
