Telkom Customer Service: Pathetic

My father passed away 7th March 2020, upon my return after the funeral arrangements to Pretoria, I tried to cancel the service via their online self service. It kept rejecting my application. I then searched the website and obtained a e-mail address to which I forwarded a request for cancellation and ID, Death Certificate and cremation certificate. The mail was returned undelivered, I obtained another mail address and have sent 2 request for cancellation accompanied with required proof my father has actually passed on! No reply except and account for R1225. I was warned also that Telkom requires 30 day notice! The credit act states quiet clearly 20 working days. I've been trying for at least 6 years to cancel my deceased mothers account, even reporting it to Telkom Customer service in Centurion Mall with no progress in the last 2 years.
