@O2 Can someone please explain why I can't change the date of birth on my O2 account despite trying the app, calling, emailing amd visiting an O2. 7 days I've been requesting this change and no-one can help. Worst customer service experience I've ever had with a company

@O2 I have tried uploading the document. The app rejects all formats. I have tried emailing and attaching the image to the Resoltion Team, they have not changed it. Do not send advice to me please, I have followed through on all previous advice and nothing has been resolved.

@Audrey25698469 Hi Audrey, I’m really sorry this has been such a long and frustrating process — especially after you’ve already tried uploading documents, emailing the Resolution Team and visiting a store. A date‑of‑birth change is a security‑sensitive (cont) bit.ly/43sZHnE

@O2 Your advice is wrong. I have called 202 every day. I have tried on the app. I have emailed the document to an agent in the resolutions team. I have visited the store. None of these things have rectified the issue
