Doesn't Telkom want business - Unfulfilled Migration to Upgraded Internet Bundle

We have been trying, unsuccessfully from the 21/06/2017 (Over 2 months!!!), to just upgrade our business Inter Bundle, but to absolutely no avail. Sakhile Ngobese, the Telkom Business Mobile consultant concerned, simply doesn't answer any of our enquiries as to the status of our request & there's no telephonic contact so we can't even talk to anyone (This from a telecommunications provider!!). This is a typical example of Telkom's shockingly poor & unprofessional service.
