Poor customer care and product service

I requested an ADSL line upgrade via the Telkom app, email service, self service and last week I desperately visited the Telkom store. Only 5-7 days sir.......NOT. Over a month now that I'm trying to upgrade without any success. Poor....poor service. Try and phone them, without success as no one answers any phones, you just have to listen to the voice on the other side for 30 min at a time and eventually drop the line out of frustration. I wish somebody can assist me.
