Remove my details PERMANENTLY

I have received SMS's and phone calls regarding collection on my Edgars account. Please note that I have already resolved this issue with yourselves AND Edcon in 2011!!! Now I am being harassed again.<br> <br> My EXISTING Edgars account number is ***196, and NOT ***866, which is supposedly in arrears. Please make sure that you have correct details before you start harassing people. Do not buy and use out of date/incorrect collection databases.<br> <br> I also received a confirmation letter from EDCON in 2011, stating that they will resolve this matter.<br> <br> Please confirm that you will resolve this matter urgently, or I will take the necessary steps to report this to the relevant ombudsman.<br> <br> <br>
