Account cancelled in Feb but still being billed

Logged a request on website in Feb to cancel service on line ***. This was not done and Ive been billed ongoing since March even though service has been cancelled. Cancelled again in March through [Email Removed] Again this was not done and again I was billed. Cancelled for the third time to Florence. Ive now been informed that the line is cancelled but have not received written confirmation. Ive also requested to provide proof that billing has been reversed and that no monies are being owed as the service was cancelled originally in Feb. Florance is not helping me and saying I must phone billing. When you phone the call centre you hold for over an hour with no response. Im not going to be send from pillar to post. This is a Telkom error and you should rectify it and provide me with proof that no account have been billed. I want the invoice showing its cancelled and that outstanding balance is zero. At Feb the account was actually in credit. Im not in SA so please do not try to phone me. I want feedback via email. If this is not resolved asap I will be logging a further complaint with the consumer complaint commission.
