On November 3rd I thought I had misplaced my cell phone, so I looked for it the rest of that day and on the 4th but could not find the phone so I placed a lost phone entry on November 5th. I received my October bill and it had that I owed $124.00 and I knew this was way to high being that my normal bill has been between $39.00 to $45.00. So I saw on my bill that all these downloads were fraudulently made to all these various game sites and porn sites. I immediately called AT&T to complain and inform them of the problem and they of course told me that I was responsible for any downloads that were made on the cell phone before I reported the phone lost so I had to eat the $124.00 bill. I had just renewed my contract and just got the new phone when it was lost so I had my old cell phone and they told me to go to the nearest AT&T store and have them put in a new sim card and that will take care of the problem. I did that immediately. When I received my November bill I was shocked to see a $299.00 bill and when I looked at how that could be possible it showed that there were downloads made on the phone after the 5th and after I had the sim changed. The rep I got was very nice and the said they would fix the problem and that I would owe $75.00 for that months cell phone bill so I paid that. December when I received my bill it showed I owed $526.00. The bill showed I was past due by $2.89 which should not have been possible being I paid exactly what the rep said. There were no downloads this time but it said that I went over my 450 anytime minutes by 897 minutes that just isn't possible yet when I look at the bill it is my cell phone calls. What I didn't realize was that when these people were downloading on my cell phone they must have used all of my roll over minutes which I usually had 350 roll over minutes. They say I am responsible for this bill but there's something very wrong here cuz it's my usual number of calls for the month. This is a disaster and I need to know if anyone else has had this problem and if they know what actions I can take on this.
