    @Robdw1983 @O2 Mine’s exactly the same, the check the network and tell me that it’s working when it’s clearly not 🥴

  • RidingWithCJ RidingWithCJ (@RidingWithCJ) reported

    @GarethTurpin @O2 Disgusting, already making horrific amounts of profit but just can’t help yourselves. As long as the fat cat share holders get what they want aye? A hike that high and the reasoning are both utter crap. Pathetic corporate greed.

  • GeekJoshJohnson GeekJosh 👾 (@GeekJoshJohnson) reported

    Well my @O2 bill is going up 17.3%. It's ok though, because it'll "help cover the rising cost to power their network". Inflation is going to ruin us all.

  • hammers10 Amanda Marshall (@hammers10) reported

    @O2 I'm in Kenya which you don't have an agreement with and are charging astronomical prices but I cannot get through to anyone for help!!! Is there anyone answering the phone? It's shoddy service. My son is trying and on hold. I hope he is NOT charged for that..

  • Ramraider20 Ram raider (@Ramraider20) reported

    . @O2 I've been with you guys for little over a year after a decade with another network and having such a huge rise in bill is a disgrace. I doubt your staff are getting a 17% payrise. I will be moving once my contract is up

  • Barnsey_21 Neill Barnes (@Barnsey_21) reported

    @djillings @O2 Switch to @giffgaff mate. They use O2 network but a hell of a lot cheaper 👌🏼

  • Graffititongue Keith (@Graffititongue) reported

    @O2 Talk about a way to lose thousands of customers.Your price increase from April is utterly ******* disgusting & a total piss take.Been an o2 customer for well over 10yrs but I'll be off as will many more.

  • ChrisWilmshurst Chris Wilmshurst (@ChrisWilmshurst) reported

    @MichaelsTecTalk @O2 Yeah, but it’s definitely time to switch. I’ve been with them for probably 10+ years now and the service has progressively got worse and worse. I can’t even hold a phone call without it cutting out in or around my house. (And I live in a built up area)

  • SirBlimelyWindy Neil Jeffery (@SirBlimelyWindy) reported

    Hey @O2 if you want to contact me with a personal offer, ring me from your customer service number or email me- a Blackburn number I have never seen before makes me wary

  • deirdre5000 Deirdre-Alexandra 💮 (@deirdre5000) reported

    @O2 Hello, unfortunately it’s not giving me a solution to my problem other than advising me to use o2 wifi which isn’t available
