MYSTERIOUS DEBITS ON MY BANK ACCOUNT

I have 2 amounts debited on my Absa bank account on the same day, R100 and R336. I have been escalating the matter since the 3rd of August. After a long follow up via email I was referred to the nearest branch. The call center agent could not give me an explanation as to what the 2 amounts were for. U was then referred to ********** who sent an email to Gugu Nxumalo, stating that the matter was escalated to a wrong department. I had no response from Gugu Nxumalo, I then emailed her directly, to date she hasn't responded. I don't see why I should go to the branch if there is a call centre and an email system At some stage I got a response from Dion Milton who also couldn't say why the money was debited.
