  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    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.

  • dartduignan180 sean duignan (@dartduignan180) reported from Culmore, Northern Ireland

    @virginmedia @O2 But not your customer service when it comes to cancelling an order

  • oharama Marian O'Hara (@oharama) reported from Derry, Northern Ireland

    @O2 hi, I’m having issues with the link sent for the 6 months free Apple Music. Can anyone help please?

  • michelle_hines1 Michelle Hines (@michelle_hines1) reported

    @O2 Hello, is there a reason that signal is so bad in WN1? This has been going on for nearly 2 weeks now

  • JeffForshaw Jeff Forshaw (@JeffForshaw) reported

    @O2 Credit where due - decided to move to Volt and ported from Virgin Mobile to 02 initial issue with security but CS for 02 was excellent (love the WhatsApp style to come back rather than wait) and the Port in went VERY smoothly. Happy customer!!

  • mbgiftshopuk MB Gift shop UK (@mbgiftshopuk) reported

    @O2 @virginmedia Totaly disappointed with customer service today, never again will be getting any more contracts from o2. Been loyal customer for years and they messed up my upgrade whixh should of come today and floor manager literally sent crap email and not delt with it. Shambles!

  • peterkin1010 Peterkin2020🏴󠁧󠁢󠁥󠁮󠁧󠁿🏴󠁧󠁢󠁥󠁮󠁧󠁿 (@peterkin1010) reported

    @Friendlytaxidr1 @O2 If you're happy with O2 then great. Admittedly the network is improving but I'd sooner have it working better and more places than it does as opposed to loyalty bribes..er sorry.. I meant gifts any time of the week.

  • sxmexne_else char⛓ (@sxmexne_else) reported

    .@O2 I ordered a new phone from yourselves this morning to be collected from my local store ‘within 30 minutes’. To then receive an email being told I would be able to go there now to receive it. I went there after 2 hours and they said I would have to get it tomorrow? Any help?

  • tomcrouch32 Tom Crouch (@tomcrouch32) reported

    @O2 I am currently in Rome Italy and have no way of accessing my data to use my phone. I’m having to use Wi-Fi only. I have gone through every conceivable action advised by your online help via the o2 app and still nothing. This is beyond frustrating. Help.

  • gems_endgame Gem🧣 (@gems_endgame) reported

    @O2 It says there’s a fault with the mast in my area. Can you provide an update of when it will be restored? I’ve only been with o2 for four weeks and lost service twice and had no reception for a week on holiday in a major tourist resort in the UK.

  • Charlot31941149 Charlotte Hutchinson (@Charlot31941149) reported

    @O2 I am trying to sort out my bill and the advisor I just spoke to on the payment line was so rude and really upset me and made me feel like an idiot for not being able to pay my bill even though I’ve been a customer for about 15 years and this hasn’t happened before.

  • LauraRiv81 Laura Rivett (@LauraRiv81) reported

    @O2 can someone contact me asap about a complaint. Getting nowhere in the chat function on app and phone! Took 2 extra contracts & regretting it now. Close to cancelling them all and I’ve been with you since 2005!
