Edgars selling debt

Some 7 to 8 years ago I settled my Edgars account in East Rand Mall in Boksburg and requested it to be closed. Its so long ago I cant even remember exactly what year. NOW after all this time I get emails that I owe them that exact amount of R 362. I am so sick of these people hunting for money and thinking we stupid enough to just pay!! How do I know I am not now listed on the credit bureau for this? <br> <br> If i phone they dont do anything about this. Their emails have a \do not reply"address!<br> <br> SICK of this nonsense now!!!! """
