I had a problem with my AOL account. A few months ago, instead of my usual £5.95 bill I was faced with £200+ !!!
When I contacted them I was told that the next month's bill was already at £150+. I told them that there was no way I had accumulated such an account and they furnished me with details. Many of the times were when the house was empty. They tried to say that my husband could be accessing it from work but as he drives a van all day & is a complete novice on computers I disputed that vehemently!!
They sent me a declaration form which I had to fill in with every line of billing and I had to declare that I had not used AOL at these times. They accepted my statement and I was eventually cleared of the bills but it was a lot of work to get there!! You have my sympathies. They admitted that it looked as if someone had definitely hacked my account...or as they put it...The account had been compromised.
