Vayama Cancelled flight reservations without warning!!!

 They booked my flight charged my credit card I made arrangements to go take care of 87 year old grandmother and booked hotels rentals and days off. I got a confirmation number and then did not receive email called them to a disconnected number then was in the line for 47 minutes to be told by a non English speaker who I barely understood that the reservation was cancelled!!! My grandmother and kids cried was probably our last chance together How unethical unprofessional and rude!!! Please avoid at all costs many people say their trips were also cancelled if you google other reviews Scammers We should sue them!!
