PATHETIC!!!!!!

I am fed up of the pathetic service from Vodacom!!! I was suppose to receive 200MB data on 1 August as part of my contract. I still haven't received it! So I went over to the application to purchase 250MB data out of my own pocket and the application failed! Waited for 10 minutes before I proceed to do it again. Bought 250MB and then checked my balance! Oh my now all of a sudden I have 577MB data! Thus the first purchase of data went through even if it said failed and not valid number dialed! Interesting! And PATHETIC! Now I must pay this double amount because your damn application is inconsistent!! PLEASE get this sorted!!
