    @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

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @Armaanilyas2 @O2 It’s so crap!

  • marcwhufc marc foley ⚒ (@marcwhufc) reported from Barnet, England

    @o2 your service has been shocking nearly 2 weeks and my daughters Apple Watch for Xmas not here. Now by all accounts best to start the order again as will be quicker and wait a week for deposit to be put back in my account 🤬 look at your dm’s I’m in them 2 replies so far 🙄

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @JayTaylor_93 @O2 I literally get two bars everywhere. It’s so bad. Really disappointed

  • joe_bignell Joe Bignell (@joe_bignell) reported from London, England

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

  • carmeyb Carmel Brady (@carmeyb) reported

    @O2 I’ve changed from Tesco to o2, keeping my number and was told it’d be complete by 6pm...still not working! Help!

  • Chez31944239 Chez (@Chez31944239) reported

    @O2 Maybe some customer service training is required for most your employees, especially the downright rude South African department I was transferred too who were downright rude and basically called me a liar before hanging up on me

  • Seano8423 Sean (@Seano8423) reported

    @O2 sort your ******* service out in deeside north Wales it's been piss poor for at least 14 years!!!! #useless

  • Chez31944239 Chez (@Chez31944239) reported

    @O2 Unfortunately it wasn't as the number is no longer held by your company even thou it was less than 12hrs before, fortunately I found 1 member of your staff that actually tried to help and didn't just hang up on me and tried his best to resolve the issue with no success

  • JudgeDewie Alex (@JudgeDewie) reported

    @RobinTheTwit @O2 I spoke to the neighbours about it but they’re a little wary of going to court - which is fair enough. If I was O2 I would just refund a customer who has had 2 contracts with you for 2 phones for over a decade for the 2 months inconvenience but they don’t want to set a precedent

  • lparkin Lee Parkin (@lparkin) reported

    @O2 your signal is dreadful! As soon as my contract is up in 6 months I’m going back to @EE 😤😤

  • greenleader1 CHUMBA (@greenleader1) reported

    @O2 i cannot wait for my contract to end by far the worst internet in the world and i lived in zimbabwe

  • JudgeDewie Alex (@JudgeDewie) reported

    @RobinTheTwit @O2 No company starts any engineering project without a predicted end date. They probably knew all along it would be 6 months so they lie and say “soon” in the hope customers don’t leave. Not suggesting the customer services people are lying. They won’t be told so they don’t know.

  • Seano8423 Sean (@Seano8423) reported

    @O2 It's been terrible in the whole area for years!! Should be pretty good on an industrial zone. Other networks have no problem. You should be ashamed of yourselves when you say your the UK's no.1 network service. Think I might have to try @EE

  • chatffinch Catherine Finch (@chatffinch) reported

    Thanks @O2. Stuck in Europe due to travel restrictions trying to keep in touch with family and you slap a £27 charge on us. Changing provider as soon as we get back. Poor customer service. Response please. #O2takingadvantage
