Telkom email not working

I have had a Telkom managed email account on the domain intekom.co.za for many years. My bank account is debited every month for this service. On Monday 20/04/2020 I stopped receiving email and the following message was displayed "pop3.intekom.co.za not responding". When this did not rectify after 2 days I phoned the Telkom helpdesk and eventually got through to an agent. After spending considerable time checking with other agents and checking online, the agent told me that there was no record of Telkom having anything to do with Intekom. I thought I would try their Webmail service but that doesn't work either! I spoke to an ex-colleague who had a senior position at Telkom to see whether he knew of anybody who may be able to help. He responded that all the good technical people have left Telkom. This really deserves a response from Telkom.
