*****ing money from my account!!!!

So my contract was cancelled and paid in full in January 2020. All sorted, no problems. Then this morning you put through two seperate debit orders totalling R629-90!!! It cost me money for the debit orders and to dispute the debit orders. I suggest that someone contacts me with regard to this. And I would love to know who signed and authorized these debit orders?? I am reporting this ***** to my bank today. If no one contacts me I will be spreading this all over social media. I'm waiting for a call.
