On XX/XX/XXXX I purchased XXXX roundtrip airline tickets from XXXX to XXXX leaving on XX/XX/XXXX & returning on XX/XX/XXXX. The purchase price was XXXX {$1700.00} ( XXXX dollars and XXXX cents ). The amount taken XXXX ( service provider/airline ) from my credit card was XXXX {$1800.00} ( XXXX XXXX XXXX XXXX XXXX XXXX dollars and XXXX XXXX cents ) on XX/XX/XXXX please see Schedules A, XXXX and B, attached. 
Since I initiated this transaction through XXXX, I called them to inquire about the over charge on my credit card in the amount of {$94.00}. Their records showed only a payment in the amount of {$1700.00} so they tried to contact XXXX @ XXXX to clarify this, with no luck. Since XXXX representative was unable to get a hold of the airline he asked me to contact my credit card company to initiate a dispute for said overcharge in the amount of {$94.00}. 
On XX/XX/XXXX, I opened a dispute online with Citi and mailed backup to support this claim. Case No. XXXX. 
On XX/XX/XXXX, I visited XXXX website in order to select seats for our trip and found out my reservation was cancelled by the airline ( please see reservation status on Schedule C attached, it reads " XXXX '' in XXXX, which means Cancelled ). I tried to contact XXXX customer service department @ XXXX with no luck. I called XXXX to verify this new information and they confirmed vendor cancelled my reservation. They asked me to contact XXXX immediately to request a refund. 
On XX/XX/XXXX we drove to closest XXXX offices located at XXXX airport to discuss the cancellation. The representative confirmed the reservation was cancelled and provided screen shot of the airline 's system, see Schedule D. 
Since vendor cancelled my reservation I needed to make sure a refund was processed so I initiated a dispute with Citi Cards Billing dispute department for the full charge on my credit card in the amount of XXXX {$1800.00} ( XXXX XXXX XXXX XXXX XXXX XXXX dollars and XXXX XXXX cents ) processed on XX/XX/XXXX, see Schedule E. 
Citi Cards billing dispute department sent me a letter resolving that the vendor did n't agree to refund my money because they said I requested a cancellation, which I never did ( see Schedule F ). 
Due to the cancellation of my reservation without my request, I had to buy a separate set of tickets on a later date at a higher price. Since my credit card company has n't credited the purchase amount to my account and it is not protecting my interests by allowing XXXX to keep the money for a service that I will not receive because they denied to provide, I 'm asking for your help to resolve this issue.
