My husband booked a flight from Germany to Nigeria with vayama on the 30th of August, his credit card was debited immediately. On the 31st of August, vayama sent a mail to cancel the flight he has booked for no reason. So, if they cancelled the flight, the money has to be refunded, uptill today been October 9th, vayama is yet to refund the money, we need the money, what sort of fraudulent act is this?
