Worst service EVER

I wanted to make an early settlement on my loan. I tried to set up a debit order for this but the Getbucks Site told me I was unsuccessful. I phoned Getbucks and I was told to EFT the money to [Email Removed] which I did. My accoynt reflected as paid up by last night as this was done on Monday. This morning I was debited again for the same amount. I contacted Getbucks and was told by a very unhelpful Bongekile that the debit order will take 24 hours to reflect and only then will I be reimbursed. This is unacceptable as my EFT reflected already last night and they cannot take a double payment. One payment HAS to be returned. I expect this to be done immediately as the last time this happened it took 3 weeks for Getbucks to return my money. If customers borrow money from Getbucks, interest is charged daily. But they will sit with our money for 3 weeks and that's okay? I expect and immediate repayment. This is NOT acceptable. To make matters worse, Getbucks NEVER removes repayments from the credit bureau, so repayments for loans settled a year ago look as though they are still being settled. Worse service ever.
