Will never do business with Telkom again

This is getting absolutely ridiculous! Have have sent in my application to cancel my contract at the beginning of April already and I have had not had any contact from Telkom despite having, phoned them, complained on their site, written on Hello Peter previously about this and going to the ncc! The NCC advised them to make contact and still nothing!!! I have never in my life seen such bad service, my next step is writing on social media and to the newspapers.
