T-Mobile is trying to charge me $78 for ringtones/downloads for my 8700g that I never asked for and furthermore never received. I have NEVER downloaded any such items in my 3 years with T-Mobile. They tell me these are valid charges that were ordered from my handset. Interesting point is they were all done between midnight and 6:00am on 12/24 . . . . while I was asleep and BB was next to me. Obviously I am disputing. Of greater concern to me is how I can prevent this from happening again. This fraud could have cost far more than $78. Anybody heard of this type of problem? And what can I do to protect myself?
