Call Centre Agents Harrassing Me

Since Monday this week i have been HARASSED by the call centre on a new Sim Card that they are insisting to send to me, due faults picked up. Funny thing is no one seems to hear that I am not using that ******* service and moved my business to Telkom ADSL, which I am so so happy with. SO PLEASE IF MANAGEMENT CAN SEE THIS, TELL AGENTS TO STOP CALLING ME, REALLY 5 DAYS IN A ROW AND STILL I GET ASKED THE SAME FRIGGIN QUESTIONS, REALLY !!!!!!!!
