Ongoing issue for 2 months

This is literally my second bad review to this company, because it seems that this is their only means of communication - bad reviews. No one answers emails. EVER. Everyday someone calls me to tell me I am R160 in arrears due to interest raised on a settled account that I refuse to pay. Every time a different person calls me, not knowing what is going on and the story regarding my last quarrel with these people. They are *********** and their personnel definitely do not have the adequate skills to communicate either telephonically or via email.
