Identity... Not worth it.

Last month in error I short paid my account by a whooping R50, since then I've been getting call none stop regarding payment. Then they reckon I owe the current month's installment and the R50, which I will pay. A total oversight but the amount of calls and harassment for R50 whereas people ***** thousands. Not like I didn't pay my account. I only short paid. which I'm going to settle my account and close it now. Good losing a customer.
