Extremely poor service

Telkom is at it again. In 2017 I was at war with this service provider. Here I am again at it again. I cancelled my contract on 15 February 2022. Yet I received an invoice of R100 due for payment. As a customer I am not able to reach or speak to any contact agents. When calling their contact center you are referred to a whatsapp whatever which is not effective at all. The only contact agents that answer calls are those of sales how ironic. Calls for cancelation are not answered they ignored.. Telkom has proven to be one of extreme poorest service providers. Be it call center and stores. They hire unfriendly and rude,unprofessional people who do not care about their clients. I am expected to pay R100 on a contract that is supposed to be terminated.
