DISGUSTED & FRUSTRATED EDGARS CUSTOMER AFTER 40 YRS

It would appear that since Edcon sold out (I think RCS took over, not sure). The service wrt accounts is disgusting. No response to e-mail & vague to telephonic enquiries. The monthly statements however keep coming demanding & threatening. Is there someone with intensive legal knowledge wrt MAIL *****, as I think this is what is actually happening. People keep paying the "small amounts" hoping the account will be closed but never happens (R200 x 1000 people = R200 000). In the US it is punishable by imprisonment. Detailed statements requested as proof of their claim never arrive.
