    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • mummycarys2010 Carys Lloyd (@mummycarys2010) reported

    I don't know why companies use @DPDgroup_news Terrible service. They have lost my new @O2 phone that should have been delivered on Wednesday and I only find out today because I have called them 3 times!! Takes 6 working days to investigate, I leave the country on 29/3 👍🏼

  • doncmccall Don McCall (@doncmccall) reported

    @O2 Hi o2, interesting this. When I get an email from you to say ‘upgrade early on us’ the truth is you HIDE the remaining to pay in the next upgrade tariff. Very poor and lies. I have £36.70 left and over 36 months all tariffs are £1 a month more expensive. Deceit!

  • danelle0204 Danelle Findleton (@danelle0204) reported

    @O2 my iphone lense has smashed, will this be covered by o2 accidental damage i pay every month? If so how long will it take to be fixed

  • Kazorina Karen (@Kazorina) reported

    @O2 would love to speak to someone who A) does not sound like they’ve just woken up B) puts me on hold for ages until I give up or C) just hangs up on me! Service is disgusting, I need a long standing issue sorted! Will never consider o2 as a network again 🤬

  • cook0563ja JC@Chipp' (@cook0563ja) reported

    @O2 for a town half way between the capitols of England & Wales I find it incredible that my O2 service continually drops from 4G to 3G. Ridiculous.

  • comte_st Dr Le Comte de St Germain (@comte_st) reported

    WHY is the phone signal so crap along most of our national rail network? Seriously, @O2 , major cross country route from Newcastle to Plymouth, no signal on most of it. Thousands of people every day.

  • angels1five Lesley (@angels1five) reported

    @O2 Yes, I know how to do this and we have tried. It didn't work. The only available network is Digicel which we can connect to but there's no internet.

  • toffeeman1971 Toffeeman (@toffeeman1971) reported

    @O2 Thanks as I requested this on 16/03/2022 and I'm already a virgin media customer.

  • BenSlat1984 Ben Slater (@BenSlat1984) reported

    @O2 is there any chance you can port my number so I can actually get some phone service - 3 days and counting! Imagine if I didn’t pay my bill and kept giving the response I get online “wait another 24 hours”. You replied to my DM earlier asking to clear security then nothing!

  • MegsHopkins Megan Hopkins (@MegsHopkins) reported

    @O2 sim swap with new phone hasn’t worked and now have no service without internet connection. Been 3 days and not clear on how to reach support. Can you help?
