Unauthorized Debit Orders - Unauthorized Charges

On the 1st and the 2nd of March 2019 I was charged a total of 240 (120 + 120) with descriptions (#Item Paid NO1 Items On) and according Kamo Malakoana it was because my account went into a minus. The account was in minus because of unauthorised debit orders that went through my account, which I tried to reverse on Friday, 01 March 2019. I reversed two 199.00 debit orders from CELL-C according to description one for Santam I couldn't reverse as it was more than 200. I called ********** 599 twice only to wait an hour and eventually had to hung up as I was attending meeting. After another hour's wait on Saturday, 02 March 2019 I was able to reverse the debit order only for another unauthorized debit order of 99.00 to go off my account. In the 14 years I've had this account I have never defaulted on my contractual obligation and do not intend starting now so PLEASE refund me my money and address the issue of ******* debit orders.
