Incorrect Debit Orders Taken

I thought that SAU was very professional since I started insurance with them. I didn't have issues until the beginning of November. The due debit orders went off on 2 November 2015 as planned but there was an amount outstanding of R24.64 due to late submission of the policy change. The amount of R24.64 was debited on 3 November 2015 which was correct but another amount of R2.38 was also debited on the same day which was incorrect (not supposed to be debited). Then on 4 November 2015 another 2 debit orders went off incorrectly, one for R24.64 and another one for R2.38. So 3 incorrect debit orders over a 3 day period of debiting. I have contacted them several times requesting my money back, I sent an e-mail to them detailing it on 9 November but no reply to date, and I sent my bank statement as requested by the agent on the phone on 10 November. They still have not contacted the bank to reverse these incorrect debit orders. Not very professional nor speedy service that I expected from them.
