Dissapointing Service

I'm so frustrated by WesBank, a payment was done on my vehicle finance account with an overpayment that was supposed to be refunded to me last week already, instead of processing my refund and closing the account like I nicely asked them to, they debit my account, now the debit was returned and no one at WesBank wants to answer who is supposed to pay for the returned debit, instead I'm being transferred from one department to the other, how disappointing.
