I have been receiving threatening letters regarding unpaid bills from O2. I have spoken to their fraud department on two occasion, the last one today with a person called Lozario. O2 obviously do not want to resolve this issue as Lozario put the phone down on me. I have sent them numerous letters telling them that the person concerned does not live at my address. Their recurring theme is that the person used to live at my address but has now moved. I explained that I purchased my house in July 1982 and can assure them that this person has never resided at my address, unfortunately as with all large organisations they have blinkered vision and cannot see past their standard corporate script. O2 customer service is appalling, I am not a customer thank goodness.
