****py Vodacom deals not the same as web page

I jave been trying to upgrade since Black Friday. I requested a call back and I eventually got hold of them, I was given mixed messages. On the web page, I could get the deal I was wanting, but the page froze when I tried to click the last step. Customercare says phone Online delas. Online gives me another story. Eventually, they try selling me a deal that isn't an option. Furthermore, they tried to convincr me that a 36-month contract is the only deal I qualify for... excuse me? Really?
