    @O2 Why do you feel it is ok to install an esim for a disabled person with mobility issues then deactivate it the next day with no warning or help? You also promised refunds for lost services.. simply to charge me more than usual. Disgusting customer care and support!

    Here's my best tech tip, at whatever cost avoid @O2 as a phone carrier, I've worked closely and don't have any faith in them as reliable service. Customer care won't answer and messed up a handset of a family member by assigning a number that wasn't asked for.

    @Ofcom How do I raise a complaint against @o2

  • ryanstanley22 Ryan Anderson (@ryanstanley22) reported

    @O2 you think it’s ******* acceptable for staff members to laugh at you on the phone and then terminate the call, your a ******* joke of a network!!!

  • Sarj007 Sarj Mistry (@Sarj007) reported
