Telkom bad service

I have cancelled my fixed land land on 30 Sept fo 30 October 2019. As from yesterday evening my line was cut. When I enquired today the technical staff said my service was suspended. The Office of Telkom say there is nothing wrong! Still I do no have any internet, line or email. They said I could keep my telkom email address, but now I am wondering if that is also a lie. I had a line with Telkom for the past 35 years. I have never experience such bad service. I cannot do any work and/or receive / sent any emails. Nobody comes back to you.
