Telkom letter of demand

I cancelled my service with Telkom in July 2021

Well done Telkom, you are refusing to send me a final invoice but quite happy to send a letter of demand. Well done!! your 102.... numbers cannot resolve anything. Well done for sending MMS messages to an old Nokia 2G phone. Well done for trying to get rid of customers that have supported youy business for more than 50 years. Well done!! Well done!!
