Vodamail e-mail stopped working

I have, for many years, been operating a vodamail e-mail account coupled to cell phone number ***. This e-mail account is linked to two devices, a laptop and tablet. Since Thursday I have not received a single e-mail, on either of the two devices - which indicates that the fault is NOT with the device but with Vodacom. I was promised that somebody will call me BUT, of cause, this did NOT happen. When the e-mail is accessed it would continually ask me for a password for both incoming and outgoing vodamail servers and would not accept my password. The system also does NOT allow for the password to be reset because there is no check question - this is because the account was set up, during installation, by a computer company. Why would Vodacom fiddle with something that was working well for many years? When the fault was telephonically reported I was told that I would receive a SMS with reference number which, also, did not happen.
