Bad Customer Service

I took a contract with Telkom Mobile 2 years ago. The contract was for R 400 a month and prior to it ending I went in store to find out if I could continue with the exact same package. <br> <br> I was informed that a similar contract was not available but that I could let the contract run on a month on month basis and that the costs would be the same except the device fee that would fall away. <br> <br> 1 month after the contract ended I was charged R 771 , on enquiry I was advised that an incorrect data bundle charge was levied and a call was logged to have this reversed. After no communication I called the call centre and another query was logged. In the second month I was again charged R 771 and on enquiry I was advised that a discount built into the contract had fallen away on contract ending hence the reason for the overcharge. <br> <br> I have now asked for the contract to be cancelled. Telkom has advised that the contract will be cancelled 20 days after receipt of notice.<br> <br> After being given incorrect information on 3 occasions I cannot understand why I should wait. Had I received correct information after month 1 of contract ending I would have cancelled immediately.
