Telkom ignore email hacking

My Telkom email account was hacked. I discovered this when strange responses were coming into my inbox, to places I'd never sent any mail. I telephoned the Telkom helpline, only to be told that I ought to send an email to their helpdesk. This I did, and eventually, after more than a week, I received 2 responses. Both told me that I ought to phone their helpline and follow the prompts. One BIG endless loop! I wrote back to the persons who had responded, explaining my predicament... with no further responses to date (more than 2 months later). I once again phoned the helpdesk, and got through to one lady who indicated that she was going to attempt to help me. But our line got cut off before I could get her name. So... back to where I was. To date I've gotten more than 3000 hacked mail returns into my inbox. And this is after I've set up a variety of rules and filters both on the main Telkom mail site as well as on my pc.

Not one bit of information has been provided or offered as to how I ought to go forward in dealing with this, never mind them actually taking any action on resolving it.
