Lack of service and lack of concern for client

After spending hours on the phone to Telkom I can only comment on the frustrations experienced over 3 year period. My landline has been out of action for 3 Years I have contacted them on many occasions requesting that the remove my landline ,is non operational,up until August 2017 the monthly charges were reversed .I constantly contacted Telkom no joy,eventually contacted Hullo Pete contact result was to contact an e-mail address that was not operational. I have now received an account for over R4000.00 and again contacted Telkom only to be told to register which I did. I was guided to the chat line and corresponded with one of their agents who because I do not type fast enough ended the chat with no response,once again I went n the chat line this time I managed to convey my problem this time I was advised to pay and they would cancel discontinue the service,before I could reply the chat was cut. I then contacted the accounts department and spoke to a lady called Lavern who calmed me down and helped to log a complaint. On top of all the above problems Telkom has discontinued my Business E-mail and once again followed all their instructions again no response. Is there anyone interested in client service?
