Debit order

I had called 4 months ago and set up a payment plan for the HOME CHOICE AND FINCHOICE. I have paid in full. I just received an email stating I owe R1034 when I call the call centre Bongivuso to ask why I received a statement when I have settled the amount on my side, and the home choice is settled but the finchoice isnt doenst make sense agent went on without assistance and dropped the call called and they dropped the call. Poor service as this is about my credit and they not rectifying the error. am very ****ed with the customer service I have received.
