Disguted Top up 49!!

Pretty much same issue as the rest!! was converted from prepaid to contract , after longest period of not hearing from anyone finally received an sms yesterday 12/02/2015 stating airtime is loaded and moments later my blackberry was wiped of contacts as well as BIS off. Enquired with Vodacom and they gave me the call centre number...called till I was blue in the face with the line just going silent! R500 airtime later no success or answer! No warning, no instructions on how it works... I want to cancel contract asap as I want my service restored, my business suffering as I need internet access. Tried looking up info on my neighbours laptop only to see the mass of people complaining!! This company is a ********** ****...non-existing call centre...now being Friday will probably have to wait many more days while my business suffers. This is BS!
