@Vodacom. What does it take to qualify?

So i am writing this review purely due to vodacom not giving me a direct answer. The issue is that i completed the necessary for a contract online, it is R249 for 36 months or R299 for 24 months for the same phone/extras. I do not agree with a 36 month term for such a cheap phone so i opted for the 24 month deal, vodacom declined my contract for the 24 month yet i 'qualify' for the 36 month deal and/or anything else, when i rep**** as to the reason they did not give me an answer. When i called customer care they told me the exact same thing, i do not 'qualify' for that specific deal and they cannot tell me why. Why dont i qualify? I have no credit issues, i have had previous vodacom contracts before without a problem. I have been a vodacom subscriber for 25+years, the least you could do is give me a reason. Not cool vodacom.
