No service from Telkom

For some years now I have been trying to get Telkom to assist with an ongoing problem I have with my email account. On the 19th July 2017 I contacted Telkom in this regard and was told a technician would call me. I am still waiting. During January 2018 my Telkom outgoing mail service stopped working altogether. I contacted Telkom on the 23rd July 2018 and was told someone would call me. I am still waiting but now my incoming service has also stopped. I phoned Telkom today to find out what was happening with this case... Ref number ********** 0. I am told to wait until someone from the back office contacts me. I believe this is expecting way to much patience from me as I have already waited 6 and a half months with NO RESPONSE FROM TELKOM. I asked to speak to a Supervisor but the Supervisor declined to take my call because said Supervisor believes I should JUST WAIT, I believe Telkom should be investigated for ***** because they sell and charge for services which they cannot provide.
