TELKOM CAN'T GET IT RIGHT,

In the past 5 years my telkom adsl internet is more off than on. Dec, jan, may and June has been the worst. My line has specifically been put in by work to work in evenings from home, but the problem is, my internet goes off around 3pm and if it goes back on, at about 10:30 pm. Same everyday for the past 2 months. I have logged so many calls, but Telkom just can't get it sorted. Everytime another story. An fiber application was done in April already, but I am still waiting. Account is through business, therefore I have to rely on the work. But Telkom's service is Ultra Pathetic.
