  • CloudXElite Megan Kenway-Head (@CloudXElite) reported

    @bethmccc_ @O2 @virginmedia They stole almost £500 from my partner. Lured him in with a contract, signed him up, got his bank details, told him he can't have a contract. Partner requested they cancel it in the same call. They said they cancelled. Said they no longer have his details. And then we got billed.

    @O2. Still no news on a signal in AL4 0XZ? That one day of work you promised is now up to 5 1/2 and counting with no information. Disgusting and incompetent service. 🤬🤬🤬

    @LutzSchueler do you think it is fair that an employee of yours at @O2 told me I could cancel my airtime contract and keep my device plan going (on a recorded line) and now I am being chased for a £700 debt before xmas and the threat of selling on the debt!?!?

  • busdriver_kenny BusDriverKenny (@busdriver_kenny) reported

    Has anyone else noticed that @O2 has been particularly naff the last few weeks, both on 4G and 5G? Not just a localised problem as it’s the same wherever I’ve been…

    @O2 I am disabled and since you have worked on the mast in St Albans my signal on my phone in my home has gone down to one bar. I may need to contact people for help. My phone keeps cutting off. Where is the service?
