fed up client

this is now the third time i have to complain regarding my account with vodacom and this is the second time that they have disconnected me wrongfully so. in December i was a victim of ***** and vodacom confirmed that this was the case, they keep billing me for a number or account that they confirmed to me both telephonicaly and via email that the account has been closed off but yet its still active. worse part is when i get a statement every month it shows that the matter has been sorted but yet i get calls to state that its still active??? they updated on my ITC record that the account is in arrears and that i have missed a payment after they admitted that the error was o their side ?? i have called in numerous times to the call center and they took me from pillar to post and have hung up on me numerous times and don't even bother to call back, now i am unable to call in as i get an automated response to state that they will me back, STILL I WAIT!!! THEY CHARGED ME R19000.00 FOR THE ********** ACCOUNT, CREDITED R15000.00 BACK TO THE ACCOUNT AND I MUST PAY THE BALANCE??? i don't know if the consultants actually have basic mathematics for people who are employed in financial institution!!
