Unauthorized debit order oh my capitec bank by a provider I don't even know.

Good day, I don't even know if I should blame capitec or this funeral service or whatever it is. On the 24 of November I woke up to 2 notification from my bank, the first one was a debit order of R220 and the second of R1500, now my p3pblem here is this is a Debi check transaction meaning it is a transaction I am supposed to receive a mandate to authorize it which I did not, I called capitec customer care for assistance and they told me to go to the branch, I got to the branch and they could not dispute it meaning I have lost R1720 and there is nothing they can do about it. I need help with this please these people took alot of money from me. I am even thinking of leaving Capitec bank because this means our money is not safe if they can't stop these from happening to their clients or assist them in getting their money back.
