unknown debit order after i clearly asked the bank to block them

I complained about unknown debit orders from my credit card, I sent that complain to ABSA action line on 17/08/2018 and only received an automated email that promised that ABSA will investigate and get back to me. I am still waiting for that response. the problem started on 12/06/2018 when I received an sms from absa requesting me to confirm a debit order. I called Absa customer service and told them to block that debit order because I don't know it. The following month I received another sms from Absa about a different company for a debit order again, I called Absa customer service to block that debit. I have recordings on my cellphone for both calls. I used to receive my statement monthly by email on the 15th but it just stopped without my concern when this unknown debits started. I only checked my statement online on 16/08/2018 that's when I realised that all those unknown debit orders went through even after I called the bank to stop them. I sent an email to Absa action line on 17/08/2018 because I needed to have a reference of my complains but unfortunately I am still waiting for their response.
