Cellular stores whereismyorder.com my credit card was charged 200 after I allowed my grandson to make a 9.00 purchase that was later returned because there is no t-mobile service in this area and im sure they knew this already. Internet

I made what was supposed to be a 9.00 purchase for my grandson on my debit card for internet service with t-mobile. We had to return the device on THE NEXT DAY, because there is no service in the area for the t-mobile internet service and this is around February 2012. I did not hear anything else from this company until my bank statement showed a 200.00 charge from them on 7/28/2012. I called them to question the charge and they told me the item that I returned in FEBRUARY was received in APRIL. I feel that even if that was possible how can they charge my debit card this account was not even in my name I just paid the 9.00 for the shipping of the device.
