Received a billing for $12.97 giving 800-883-8327 as a reference in the description of the charge on 8-14-08.

I did not use this line and the charge is fraudulent.

I have checked back records and found a charge of $19.94 on my credit card that was paid by accident by us to twx, checking back we did not make an order from them, I don't know who they are,but the phone number is
1-800-883-8327. Who are they???

This was not a call on a cell phone, but a removal of funds from a credit card from this number. I checked with the credit card co. they have received many complaints about this number. I phoned the number reply messages from TXM(?) says that it would like my name and home telephone number to let me know about a delivery of goods to our address. Never ordered anything on that day either on line or on a cell phone.
Credit Card Co. are on to it, it is a fraud.
