Data not loaded

Vodacom just need to get rid of their just for you promotion, time and again I've purchased just for you bundles and they are never loaded, just this morning I bought data using the *123# service and the data was not loaded I had to buy again using the app. 3 times I bought 20min talk time n it was not loaded, the last time I had to call for them to refund me. Another thing there is something called smart offers on the app they will offer 50mb forR3 then take R5 or send an SMS saying dial *124# to buy 50mb for R4 then they take R5. Honesty we cannot complain about the same thing everyday please fix your system because it really is frustrating as much as it's small amounts that one has lost counting back I realize it's a lot.
