Telkom doenst respond to my request

I have been trying to contact telkom mobile department to cancel my contract, I dont get any response from them, I have logged a dispute and even try sending them messages.

The problem is this contract has expired around a year ago and since then I dont have the sim card any more and not been able to cancel the contract either.

I am not happy about this kind of service, because they are fast and easy to get a contract from but after service has only been a struggle for me.

in the past I would have recommend their service to anyone, I also found their LTE in Gauteng areas is amazingly fast, but struggling like this to get service after sales is not something I would want anyone to sing up for
