Never billed, suspended but still want to be paid

i took out a telkom mix contract last year in March which included a land line and mobile phone. once i picked up the phones i used them for a month. telkom never debit from my account as stated in the agreement. they also never mail or post a invoice so i could do a payment. three months went by without them debiting or invoicing. so i went to the store to find out what was the issue. the consulatant that helped me get the contract didn't have a clue of what she was doing. the manager couldn't locate the agreement. after many threats the agreement got to me after 6 months in that time my account was suspended because of non payment and i could not use either phone. i didn't receive any minutes but the company kept billing me each month but the didn't send invoices. i went to my lawyers to assist and they didn't get far with this incompetant staff at Rustenburg Mall. after a while i received a mail that Telkom was cancelling the contract and that they wanted 12000 to settle the account. i never received any minutes since the first month nor invoices and they didn't call to find out what was the pproblem. Marinda SAle was the consultant which is the most useless consultant i've met.
