Uselesss service

I have never ever in my life experienced such terrible customer service at vodacom centurion mall!!! After waiting forever in order to see a consultant i was helped.... I explained my situation and this arrogant little man told me i should rather monitor my phone usage. I informed this wonderful consultant that as soon as i load airtime or a data bundle within 5 minutes my balance shows a zero balance. This started 48hours ago. I just loaded 250mb in front of einstein and immediatly a zero balance and the only advise he has is that i must monitor this!!!!! Fed up and irrate!!!
