Harrasment

I contacted Cell C on the 24/4/2015 to confirm cancellation of my contracts after not getting my queries resolved for almost 8 months. <br> <br> I recieved a letter on that same day confirming that both accounts have been paid up and closed. I called him to confirm that I will no longer be contacted by them for any outstanding money's and that they will clear my credit record.<br> <br> now after weekly phone calls and sending that same email back to them I have been handed over to a collection agency.<br> <br> I am waiting on the national credit regulator as to what I am to do next, as this has now become a very serious problem and I have no other means of dealing with people who are totally incapable of doing their job!!!
