Cannot Cancel a Contract

I am trying to cancel a contract I have with Telkom.

I sent the cancellation request on 2017.07.31. Now the normal response time for Telkom is 21 working days.

I followed up on my cancellation request on 2017.08.10, and the lady said she will issue a mail on the system, but I will have to wait for the 21 days to laps.

I followed up on 2017.08.23 - but again the Call Center attendant advised me that there is nothing that can be done, I need to wait for the 21 days to laps. I cannot even follow-up if my mail has been received, only after 21 days can the matter be escalated.

I called on 2017.08.30 - and of course the contract has not been cancelled. The lady said she will send and immediate request and it will be cancelled within 24 working hours.

I followed up on 2017.08.31 - contract still not cancelled. The lady asked me to send a mail directly to her and she will send it though. Due to it being an internal mail, it will be auctioned immediately and I can follow up within 48 hours.

Followed up again on 2017.09.04 – contract still not cancelled. The gentleman I spoke to asked me to follow-up on my mail sent and copy him in.

Sent a follow-up mail on the morning of 2017.09.05 – no response received.

Called the afternoon 2017.09.05 – the contract has still not cancelled. The lady told me that the Retentions Department needs to call me. They can do nothing from the call centre.

How am I supposed to get the Retentions Department to call me?!

I am definitely never opening a new contract with Telkom – it is impossible to cancel it!
