Unhealthy Customer service

I have been using Telkom pocket router for almost a year and half without any benefit whatsoever due to weak signal. I was told that it’s because my SIM card has a chip which I failed to understand as it is always attached to the router.

I called Telkom to cancel my service in the mid-February 2024 and their last debit was supposed to be end of February 2024. However, they kept on debiting my bank account until today and they are even saying that my account is in arrears because I had to reverse the transaction as I have already cancelled my services with them.

Telkom is still the old same ccompany with miserable customer support, as much as I would love to support them, their unreliability and lack of customer support have made me regret using their services!
