Locked out of VMO2 accounts

Over three weeks ago I answered a call from O2 offering a discount and free gift. Although a generous offer, it seemed a bit suspicious and I reported it at my local O2 shop. They made contact with their fraud team who immediately investigated and locked the account. One week later I discovered that my Virgin Media account had now also been locked out. After multiple calls to both Virgin and O2, many of which promised me resolution within 24 to 48 hours, I am still locked out and nobody can tell me why.  Last Thursday I was told the issue had been transferred to the Escalation Team (for the third time) and that I should wait 24 to 72 working hours for resolution  This time period elapsed yesterday so I contacted both O2 and Virgin again, one of which told me that I must now wait 5 days, and the other 15 days, before the accounts are unlocked. Can anyone let me know how I can reach someone in VMO2 who really knows what they are doing and who can hopefully resolve the issue?
