Poor service from Absa bank

After paying booking.com and never received confirmation of booking, we phoned Absa to cancel payment. They asked for detail about transaction, but accordung to them, it was not enough. It is not possible to call Booking.com because AI can't help. We lost all our money and Absa don't care about their clients. After doing everything they asked for, we just got an email that said that they rejected our request. Poor service or rather no service at all from Absa bank.
