@MichaelaPontiki @O2 We would never go back to them Worst phone company EVER #AvoidO2

@O2 so upgraded to 16 pro, though now apparently I have used 157GB of data since 26 December! I apparently have also sent 42,000 in the same period. I have never used more than 25GB per month, but #O2 apparently think these figures are correct! #poorcustomerservice #avoidO2

@O2 #O2CustomerServiceSUCKS #NeverSwitchToO2 #AvoidO2 #O2IsTheWorst

@O2 again….gross incompetence, called to set up a payment plan for a balance that is of YOUR making, then I get told I need to wait till it is passed to an outside agency before I can do that!! #notsurprised #lackofcustomerservice #avoido2

@O2 Happy Monday. How about providing a satisfactory customer service that does not lie. #avoidO2

Nice one @O2 have asked for an unlock of old phone. To be told I bought it from virgin. Never had a phone ever with virgin. #poorcustomerservice #avoidO2

....since I logged a complaint with @O2 but I still am waiting a response from the complaints team, it shouldn't take 17 day from my first tweet and 52 days since you incorrectly disconnected my number to get a resolution! #terriblecustomerservice #avoido2

@O2 great way to treat customers just hang up on them #avoido2 issue been going on since November 2023 @StephenNolan

@O2 so I have been 'migrated' to O2 from virgin - my god what a shit show. Currently at 4 hours of being tansferred and repeatedly cut off whilst trying to pay a whopping £6 bill. I have never experienced such shambolic, rubbish and rude customer service in my life #avoidO2

To add to the pain of being directed to the wrong team, they CANT transfer me to the right team. (Due to a system “upgrade”) They also CANT get anyone to call me as they can’t make outbound calls. I’m soo utterly fed up with @O2 All I ever get is “try again later” #AvoidO2 (3/4)

@O2 you're a joke of a company and I'm not even a customer nor have i ever been one, your fraud team need to sort their shit out. #avoido2 #o2areawful

@O2 shocking service I have 5 devices with you my signal had completely gone because you’ve not said there isn’t 5g in my area after 3 months, then to have the phone put down on me #avoido2

@simonsanders1 @O2 @BBCWatchdog Im a victim. Waiting for it to be resolved. They wont even look at my case. Been 4 weeks. Credit rating being effected. Im livid. Never been with O2 and now never will @EE have never let me down. #avoidO2

@O2 frankly shocking customer experience after 2 weeks. Double billing, lack of customer service. #AvoidO2

@O2 how can you take payment for a phone that was never used and sent back & then tell me you're taking another payment! Where's my money you owe me? My calls always get cut off too... funny that 🤔😡 #avoidO2 #badcustomerservice @EE where you at?

@O2 unbelievable. You reply to people's tweets to DM you but then ignore the DM. the worst customer service in the world. #AvoidO2

Very sneaky @O2 charging me twice in one month's phone bill for the next 2 monthsAmazon music after my free add on ended without notification #dirtytricks #avoido2

Welcome to the last few months of trying to use my phone with @O2 . Even on 4G it is too slow to use. #o2 #avoidO2 #4g #5g #phonenetworkprovider
