Bank account Triple debited

During last year June I found that Engen Lotus had debited my account 3 times for the same transaction for R200.04 being the 2nd, 3rd and 4th of June 2015 respectively and on the 30/05/2015 for the amount of R228.04, I then queried it with Avashnie who told me they were aware of the problem and produced 1 receipt no: 204774, she then told me she will query the matter. After being given the run around and giving in bank statements 3 times which they conveniently lost the 1st two times and being aggressively dealt with by the manager shaun I have still to date have received no resolution and am being given the constant run around as to the owner being overseas or in Cape town. Why does it take Engen 1 year to refund my money. I wonder how many people are unaware of their garage or bank cards are being repeatedly debited! The public needs to be aware.
