    @O2 s costumer service is just appalling! No one cares to help. Will not be renewing my contract!

  • jimmyll04218854 jimmy lloyd (@jimmyll04218854) reported

    @O2 I’ve done this about 15 times. It’s multiple postcodes. It’s not specific to one location. You can’t fix it. What would be ideal is if you could release us from our contract so we can go back to @EE or @VodafoneUK who have provided us with much better coverage in the past.

    @O2 #worstnetwork hassle me about an upgrade but an hour later still can’t get an answer in your call centre !! Goodbye @o2 hello to any network bar you

  • rachael__coutts Rachael (@rachael__coutts) reported

    @O2 just a warning to everyone to never go with o2 for any kind of business! They don’t deserve your money. Been a customer since I had my first phone and they couldn’t care less about you or any problems you might have. Just a shower of money grabbers really!

  • ripinmypants Ryan Davies (@ripinmypants) reported

    @O2 It seems as soon as I hit any town centre the signal just goes terrible says it has 4G but never works like it’s in traffic (to many people using it In the same area ? )

  • socoedjones Sophie (@socoedjones) reported

    @Matthew_Wood85 @O2 I moved to 3 from 02. Signal was great for 6 months or so. I can't get signal in the town centre now. Would love to know what's going off.

  • chuck_lberry Rob (@chuck_lberry) reported

    @Shireen_5 @O2 Been with o2 for years and never had anything!

  • lucyolix lucy (@lucyolix) reported from Salford, England

    @O2 is the signal down in Salford? Data isn’t working and the signal is either none or just one

  • CagedAlice Flailing prettily (@CagedAlice) reported

    @O2 My phone keeps showing emergency calls only, is this likely to be the Sim failing or a issue in the area?

  • SaliWho Sali Owen 🏳️‍🌈 (@SaliWho) reported

    @jimbobswansea @O2 There’s only one conclusion: O2 is a haunted network.
