pathetic service

I visited the vodacom shop(langebergmall mosselbay)to increase my data bundle on me and my wife's cell contracts with effect 1/1/16. The employee told me that the system was down and she could not make any amendments. I called her (lady working at langeberg mall- vodacom )the 29th of December 2015 to remind her of the change, where after I was informed that their system was once again down. She asked me to call back later, I however asked the lady to call me back when their system is working. She called me back where after she confirmed the monthly data bundle was increased to 1gb p.m from 1 january 2016. I then dropped in on the 31st of December 2015 at the vodacom shop in Somerset mall to confirm that my request to increase my data bundle was processed on their system. The guy confirmed that it was in order. However on the 1/1/16 the wrong data bundle was loaded on our phones! Tried to get hold of a agent but after 25min I gave up.My next call reached a consultant but when I started to explain my problem she put me through to the customer review without listening.the next consultant told me their syst. was down, and when I asked to rate the services, I was put on hold!
