This is a bill from what is called a crammer/scammer. Most carriers allow these charges to appear for unwantred services because they get a big cut. (The scammer claims to TM you ordered this service from them.) Although TM will not verify with users first to see if they ordered these "services", they now claim 611 CS people have been instructed to remove these charges if the customer complains. IF the CS person tries to tell you you have to call the scammer (who normally can not be contacted) tell the CS person that TM has announced CS people have the authority to remove the charge and block that scammer.
You can also block all such scams (or most) yourself by going to your account and blocking all "premium" services. Be aware that might block some text services you want (there are a few people that do.) CS can do this for you as well.
If you still have a problem, come back here.
