Poor service

Worst experience ever. Booking.com requested proof of payment for them to be able to refund, I did that and they came back to say they want to verify it on my statement i provided them with that. Payments were made from two different banks. Drama from Booking.com one bank shows that it is a Zar(Rand) bank account other one do not state. Now Booking.com will not refund up until i provide the statement that will show that the funds are in ZAR(Rand).
