****ed off client!!!

A few months ago I purchased a funeral policy with Capitec Bank. The debit went through fine for the 1st couple of months. At the end of March my debit did not go through. I called the call centre to find out why and had the call centre agent debit my account. At the end of April I received an sms informing me the debit went through successfully, as well as the funds were debited from my account. At this point I had jus received my salary so there were sufficient funds in my account. I went through my app this morning only to find out that on my policy it shows the debit for the month of April did not go through. I called up the call centre only to have the call centre agent tell me that my debit was unsuccessful, which once again does not make sense as there were sufficient funds in my account as well as I has received an sms informing me the debit went through successfully. I went through my statement and it shows the debit was successful. So what is going on??? I want answers or all my premiums paid back in full or I will be taking Capitec Bank up to the Ombudsman for this. I can be contacted on ***. Name: Krishennvellie Naidoo. I demand immediate confirmation as to what happened!!!
