Problems with bad Telkom service.

On the 1st of June I opend an account at Telkom.On the 2nd I cancel the contract.I had an online chat with a guy named Londiwe.He told me that there will be no cost for cancelling the contract because they have a 7 day cooling period. On the 5th of July I recieved an invoice of R598 and they deducted the money from my account.I reverse the payment.On the 12th of July I send Londiwe and email with all the chat that we had about the 7 day cooling period.No feedback. Today the 4th of September I received again an invoice of R800.70 from Telkom.Adding a R202.70 for Rejection fee.Total invoice of R800.70 for just opening and cancelling a contract.After telling me that there will be no fee.
