Telkom Over billing

2 Months back i fell short of my Account of which i put up to date the end of last month by making the required payment. A week later my phone was blocked again and the reason was due to none payment that i had already made. After numerous calls made to Telkom my lines were eventually unblocked. Yesterday again i get a notification stating that my account was in arrears and now i am going to be billed 4 times the agreed contract amount and i cant even speak to a consultant after numerous attempts. I've had to put up with this Telkom not having network bull**** for a long time and now this. This is just utterly disappointing and hurtful at the same time. Its just **************** more so cause i cant even be given an explanation as to why.
