Breach of contract

I've upgraded and ported from cell c (autopage) to Vodacom (autopage). Because the smart m package at Vodacom is a open contact I've asked explicitly if I can block my data and airtime as well as top up my data and airtime and the consultant said yes. When I got the phone and tried to top up my data I couldn't. I called autopage customer service and the consultant said we cannot top up or put a block on the data and airtime. I called a second time on the 31st December 2015 and the consultant said they will look into the matter and come back to me by Tuesday 6 January 2016, as of yet I haven't received any phone call or email from them. I wouldn't have upgraded to the contract if I cannot top up my data and airtime.
