Poor service!

I went to Telkom store Walmer Park, they were busy with the migration(upgrade) from 4meg ADSL to 10meg wireless fibre..they then informed me that the system sees me as a new client so I will be paying R899 per month instead of R759 per month what Telkom offered me over the phone at the call center...then I told the lady to stop the process I will get in touch with the call center again. After that the struggle began. Left messages to call me back and at one time the person from Telkom that called me didn't even know that wireless fibre exist.. would've get someone to call me back within in five min...well it a week later and no cal as yet...
