Then deduct money and not update the payments

The company contacted me in April regarding my TFG account we made an Arrangement that l will pay R450 for 6months via Debit order fine ever since they are deducting the balance is the same payments are not updating when l contact them they are making an excuse about the system that TFG is giving them problem when l contact TFG they are sending me to ResolvAS telling me that l must sent proof of payments to them while they are deducting on my bank account, if l call the their system picks up my number then they drop the call l know their consultants by name they are slekem l would advise some to pay them if your account is handed over to them.
