Cant seem to get my Telkom Service Cancelled

I went into the Telkom The Glen store on 27/03/15 and completed the cancellation application forms. Wade told me that I will receive a ref number when the application is processed. Almost a month later and I still haven't received a ref number and the line is still active. I requested that the line be suspended immediately as we were moving out and the new owners were moving in but I was aware that I was still liable for a months fees but I just didnt want to be charged for calls that the new owners made. The line is still active and not cancelled. I am not willing to pay for and additional month because someone at Telkom is ***********. I gave my months notice. I cant believe that Telkom delivers this type of customer service. I have tried phoning the The Glen branch and the 10210 but I get no answer.
