Telkom Call center bad as hell...

for 6 months Telkom billed me incorrect for a package that I signed up for. I contacted their billing department who then gave me a case number. I were then told to contact sales who were suppose to change my package to the correct one. I were told that this was done and there is nothing else that I needed to do. I waited for the 7 - 14 business days as per Telkom agent for the matter to be resolved. On 10 December I received an sms notification - "Your case no ***6 is resolved. When I phoned today the agent told me that my package were not changed and I need to contact sales again to have this resolved. I now can not even phone any other number other than 10213 for billing because my account is suspended. What will it take to get competent staff at Telkom. I now see why so many customers just want to get away from Telkom....Would appreciate it the rating on Hellopeter page can actually have a negative rating....
