PNC Bank Credit Card Complaint

PNC Bank Credit card department,

Transaction issue Ohio

On -/-/2015 a transaction conducted at the - in - was swipe for - services as $ --USD instead of -. The Resort as admitted to the transaction error and contact my bank to rectify. I filed a dispute with my bank on -/-/2015 dispute number -. The only thing the case worker at the bank did was get a copy of the incorrect ( swiped ) transaction and has refused to credit back the difference. This is gross incompetency and/or the bank does not have the correct qualified employees working to resolve consumer complaints. I explained the transaction in question was an error and so did the Hotel, yet no follow-up nor verification beyond getting a copy of transaction was done by my bank. I have copies of the final hotel bill showing billing was -, emails from Hotel explaining the error, and names of individuals at resort vainly trying to resolve this with my bank. My bank has not responded to any letters from the resort 's accountants and bank to have this resolved.
