Digital Vmail, Inc., MyIproduct Imail, Regional Commerce Svcs, Triple Three Inc, ESBI and OAN, Unauthorized charges to my AT&T bill - $47.09 and $9.50 Internet

Two additional statements came with my AT&T land line billing. ESBI and OAN are billing services for the following companies: Regional Commerce Svcs, MyIproduct Imail, Digital VMail, INc. and Triple Three, Inc. When I called AT&T to find out what all of these charges were, (basically $14.95 each, mo. charge) they said I had to call each number to cxl and credit. I never authorized any of these companies, I don't even know what they are. It took me a very long time on the phone to cxl and I found out that a person by the name of T.Thomas had authorized these charges. I do not know this person, but now understand that this is some kind of a scam going on.
