CANNOT LOG INTO MY TELKOM e-MAILS

On 15 June 2018 I tried to access my telkom emails using Webmail.telkomsa.net do Messaging, I got an error stating the my account is in maintenance mode and therefore I could not log on. I phone Telkom at 10210 reported the fault, advised by consultant that I must clean my computer from viruses and Telkom will re-connect my inbox. When I tried to logon, I got a new error stating that "your session has expired, please login again." Talking to Telkom every day for hours he logged an incident to level 2 support and assured me that they will assist me. With every phone call the consultant made promises that the line manager will phone me back and that the fault has been reported to the IT department. It is two weeks now and there is no hope what so ever that I will be able to log into my e-mails. I have a business to run, end of the month, etc. etc - I really don't know how this problem will be solved because Telkom personnel is absolutely not be able to solve this type of problem. Can you please assit me? Regards
