Be prepaired when buying from Webuycars

Thought it was a good idea to buy a car for cash. Had to send P.o.p. 4 times. Next morning.. its now 11am, have 21 ***** and spam calls which I get 2 a week. No direct answers if i want to know if i can fetch the car. Then the pvt no's start coming in to tell me no funds reflect, i should pay again and once (or if) a double payment is on their books, they will refund me.

And i cant even pull out of the deal.
