@O2 I have had no service on my mobile phone for the past month.
I cannot make or receive any calls on my O2 mobile and neither can my 4 family members as they are on Giffgaff which is on the O2 network.
I'm very disappointed with @British_Airways , both in their services and in resolution. My flight on 26.10.2023 from Gatwick to JFK was cancelled as I arrived at check in, no explanation was given. 3 months later and no response to claim for compensation!
