Bad service

So yesterday I went to a Telkom branch at Kenilworth to cancel my contract. Only to be told I must contact there Contact Centre as they don't offer that service. Today I phone and finally get hold of a agent who assisted me. He then let me hold on for almost 30 minutes whilst waiting for a request or whatever number to finalise the cancellation. In fact I had to put down without getting a request number. My contract must be cancelled effective from 1 December 2023 effectively. Whenever you cancel a contract with Telkom you get the most pathetic of service. It is not how you sign me up that counts but how you treat me when it matters the most...In this case with the cancellation.
