I attended a presentation in XXXX, and the company ran my credit card for almost {$31000.00}. I did not authorize the charges. I revisited the merchant after seeing the charge, they provided me a letter stating they would refund my monies. this never occured. I called Citibank my card issuer, opened a fraud dispute at the customer service reps advice, heard nothing until XX/XX/XXXX where the case was closed as they stated this was not fraud it was billing dispute. I did speak with the investigator, she asked me to send in a notarized copy of the situation and then I opened the billing dispute. Weekly I have been contacting Citibank with no resolution, and this week they told me that too much time has elapsed and they could not assist me. there was not any moment I waited longer than 48 hours to return any documentation they asked for, and the initial charge back was open within 10 days of the charge. Since XX/XX/XXXX the merchant has disconnected their phones and removed website. I have asked the issue for arbitration, and they have told me I can not request arbitration on this issue as they need to open arbitration with the acquiring bank.
