telkom *****ing my money

Telkom is costing me money on a cancelled line - i logged a request to move my line to a new premises before moving. The imaginary technicians decided that they cant put up a line. since FEB they are charging me my full bill and i have phoned in every month since then to cancel my account yet i get a new account every month and even has reconnection fees on it too when i am just trying to cancel but they always put me on hold for an endless wait while they "request a cancellation" which is also costing me my airtime. then they keep sending bills again

Today i have made my 5th cancellation of this account which is now tallying up to an enormous amount while they decided they do not want to assist us with transferring the line and say that they cant refund me the moneys that they have received for the past months from feb till now because the account is active (although this is their hold up as i keep begging them to cancel the account)
