Ridiculous service from Vodacom

I wanted to port two of my number to another network so I called vodacom cancellations. They convinced me to keep my number with vodacom by promising 1GB or 2GB free data every month for 24 months on my contracts. They gave me 10GB once off data for the month. When I checked my contracts today there was no sign of the promised data. When you call the call centre you hold on for eternity without anyone taking your call. This is plain ridiculous and very frustrating. Now I have to go through the nightmare of trying to get hold of someone at the call centre to explain what's going on. This takes up a lot of time. The lady that did my upgrade I ever regret doing business with Vodacom.
