My friend bought two round trip tickets from NYC to TLV from a random OTA on a Chase credit card. After he completed the order the website page never showed any confirmation number or any indication that the order went through. He also didn't receive any email from them. With no indication that the order went through he assumed that it didn't work and went ahead and bought tickets from a different source. 10 days later he received an email from the original OTA that his flights had been changed...
He filed a dispute with Chase but the website claimed they sent an email at the time of purchase and the tickets are non-refundable so Chase sided with them.
Is there anything he can do at this point?
