Absa activate double debited me

On the 22 Feb my bank account was double debited and amount of R3605 instead of R1802. Monday morning I sent an email and called them and was told it was a system issue. Today is the 27 Feb I haven't received my refund and no one has the decency to inform me on the progress of my query. My order debit orders were not paid due to this inconvenience by Absa. As I am drafting this I have been on line for over an hour and no one is answering their calls.

I don't think Absa know how to treat their customers fairly. I have been inconvenienced by them and now I have to bare all the cost due to their system errors.

I am so annoyed.
