All i need is a cancellation letter

I am so fed up of calling this call Centre been put from pillar to post , all i need is a letter stating my account is disconnected , spoken to almost 5 consultants and none comes back. Lerato promised me 3 hrs ago she will mail it and Gordon an hour ago said he will follow up.<br> If this is the service i get than really why would i even bother getting any dish , a client like me who is in a minus balance , they owe me money , i am not even fighting but guess what no response. I am tired now i want my money , the letter and all ties cut with you guys.
