Discover Credit Card Complaint

Discover Credit card department,

Credit card protection / Debt protection Florida

On - -, -, per my - - statement, Discover Card hit/posted my account ( ending in - ) with a charge of $230.00 from - Car Rental, which I did not make, and submitted/attempted 7 times by the vendor and Declined 7 times by Discover because it had been attempted on a prior account ( ending in - ) which had been cancelled in - for reasons of Fraud. Nevertheless, eventually, Discover accepted the current charge to account - from the vendor, paid the vendor, transferred the charge to - closed Discover account - to active Discover account - and is now trying to collect it from me saying the vendor 'pushed ' it through even though they ( Discover ) declined it repeatedly. How can this possibly be? ... or even be allowed? The frustration I have gone through with Discover is beyond belief, not accepting responsibility for what happened. Discover should be reprimanded in the harshest way for a system that is allowing such a financial transaction being fraudulently passed on to a Consumer and on an Account they know is not responsible.
