Blacklisted Email Address

My business email is blacklisted as spam. Despite numerous complaints to Telkom technical, nobody knows what is the problem. I had to change my software and the problem persists.<br> Called again on Tuesday, 19 April 2016, spoke to Vernon as per reference *** who escalated it and assured me in 24 hours I will get a response. NOTHING!!!<br> Called again, was advised by a consultant that Telkom is having a problem with Outlook and I should use webmail. <br> After logging into webmail, I do not have any emails available. The consultant then escalated another fault as to why my emails are not downloading on webmail.<br> <br> Being a businessman, and this being my only business email address, this problem is very frustrating. <br>
