Product: Credit card

On XX/XX/XXXX, with my Discover card, I purchased a {$650.00} plane ticket from XXXX with XXXX XXXX. XXXX told me had 24 hours to cancelled the ticket and I had to do so through XXXX because they dont handle cancellations. I immediately requested the refund after the purchase because they added additional fees and did not disclose the itemized reason for the charges. Also, it took them an extremely lengthy time to send me my receipt of purchase. I felt uneasy with the purchase and ensured to cancel on same day. I also, next day, reached out to Discover to try to address my concerns and that I felt something was wrong with my purchase from XXXX. Discover informed me that I had to wait for the processing bc something the charges fall off after its cancelled. I waited and the charges posted. I still never heard from XXXX  or XXXX about my cancellation or refund so I filled a dispute with Discovery that they soon closed stating the changes were valid. I am not challenging the validity of the charge but not receiving my refund Discovery refused to assist. They told me I had to resort to outside resources. I did make contact with XXXX and found out that they did issue my refund on XXXX/XXXX and it was sent to a XXXX XXXX XXXX ending in XXXX. XXXX also informed me that the cancellation notice was sent on XX/XX/18 to a XXXX email that was submitted with my booking. I have provided documentation to Discover and they still havent offered me any assistance. To date they havent shown me any documentation of information that they received from XXXX. I have uploaded multiple documents to my dispute file but they closed it even after I had informed being unsatisfied and didnt want it closed Furthermore I have made multiple calls to XXXX and talked to numerous supervisors who states they are aware that XXXX did issue the refund back to them and still no refunds has been issued back to me. To date, I informed Discovery that XXXX collected twice on the purchase. They received funds from XXXX and from my Discover Charge. XXXX is aware of the dispute and that Discover closed it under false intent. Discover said XXXX told them my ticket was non refundable which is false. XXXX knows my dispute was closed and have nothing else to support me. Ive told Discover this and provided them with Copy of my receipt but they seem to more interest in closing the case. I am currently out of {$650.00} and XXXX collected twice almost {$1200.00}. Ive called XXXX XXXX cant even mention the number of times. They placed me on hold and tell me they are escalating my case to management for the refund but no one answers the phone after being transferred. Im exhausted and tried it this point and in dire need of assistance with getting my refund. XXXX had issued. I was confused why my email and charge card information wasnt issued to XXXX with my booking and no answer to explain it. Please help me! It had to comprehend nit receiving my refund but even worse if I had kept the ticket and XXXX had made any changes, I would not have received the emails notifications because XXXX placed their email and charge card information in the booking. Im lost for understanding. As you see on my receipt XXXX has my email address.
