I recently swopped to O2, but upon finding out their signal in my area is worse than my current provider I cancelled within the 14 day cooling off period. The cancellation took place almost immediately. O2 have today gone ahead with the porting off my existing number, in effect terminating my old contract with Virgin and leaving me without any phone number or active SIM. Numerous phone calls, where I have been cut off, and I'm told they can not give me a time scale when this will be resolved. As far as I have been told I can not rejoin Virgin under my old contract.
