Bad customer service

I called Telkom to inform the agent I was talking to over the phone that I wish to close my Telkom phone contract and she told me that the account was closed and I should make sure that I have R1129. 00 on my account (as a last payment that will be debited on the last day of October).

As payment was successfully made. On the last day of November a money was deducted from my bank account from telkom R689 05. When I went to the store the lady from Telkom said I should contact the insurance company and cancel the insurance with them they can't call on my behalf (she gave me a number that doesn't go through 080 033 444-saying the company name is Wwwas). The lady was rushing to go to clicks. Am not happy with telkom and they service I received from the lady and the fact that we have to call the insurance company when the contract is over buy when we take phones we signed up for insurance as we apply for phones (customers are mislead by agents and the next thing we are going to be handed over cause we have to pay for money we know nothing off) ruin our credit profile. Telkom is not professional.
