Vodacom upgrade dept unreachable for 2 weeks

I have been trying to do a telephonic upgrade for almost 2 weeks now. Every time i am told I am on the old system and someone will call back. Once someone did, call got droppex, tbey called back, call was dropped again, and theye never called back. I called again, and waited for the next ppromised call back. Nothing. Yesterday i called again, and was promised another callback which never came. I was promiaed a follow up call by thr consultant. She obviously also forgot. Maybe af lter about 25 yeara its finally time to switch networks?
