  • timoFK TimoFK (@timoFK) reported

    @Stephen_Woods @O2 I have absolutely no signal or service and after an entire month, numerous calls to @O2 their complaint resolution is "feel free to leave us when your airtime agreement expires in August." Shockingly poor customer service

  • SimSpeaks Simeon 🤙🏾 (@SimSpeaks) reported

    @its_me_agx @O2 I’m with them and I get a signal everywhere apart from in my house

  • Nettwerk Nettwerk (@Nettwerk) reported

    @StuLittle1972 @O2 O2 isin't customer friendly company. I had bad expierence and now few weeks ago my sister's husband as well.

  • KVLATTO 🎰 (@KVLATTO) reported

    @O2 i bought a new sim from the store to put in my phone yet it’s coming up with 0 bars so i can’t do anything. can you help activate my sim?

  • Ad_Richmond Adrienn Richmond (@Ad_Richmond) reported

    @StuLittle1972 @EmergMedDr @O2 Bad advice imo. I would still settle it because it can still taint her credit score. As silly as that sounds, credit scores are based on a tick box list. Any unsettled debt or late payment can reduce the score.

    @O2 youse are so cheeky yeno worst company ever little rats

    @StuLittle1972 @O2 I'd say go ahead and make them acquire the court costs. It'd never get there, but the time spent trying, or even just getting debt and legal departments to review it all would cost far far more. And as they've now refused to take the payment....

  • grime_vintage ForzaTottenham (@grime_vintage) reported

    @rp7673 @O2 @EE I was with EE for ayears they were awful, changed to o2 (much more prestige company) and was like night & day, however the timing of your switch plays a part as just lately there’s been problems. But generally and proven o2 are better (more towers / stronger etc)

  • coolnavnit Navnit Punj (@coolnavnit) reported

    @FredSmi22494411 @O2 Yeah, regretting my decision to port in to @O2. Worst customer service!

  • StormCloud97 StormCloud97 (@StormCloud97) reported

    @O2 I have great signal but my ping is all over the place one moment it's in the 20 - 30 ms rand the next it's in the 200 - 400 range and while I use my phone as a hotspot a lot and use a lot of data this happens on my phone and on other devices even when connecting the via LAN
