affordability

went to game for VODACOM special for 2 tablets for R149 per month contract. I wasnt succesfull as per the system to qualify for contract gettin 420 points but I qualify for 1 tablet with no data for a contract of R149 per month. This make no sense. No explanation or anything. I struggled to get stock at Game. Got the stock now I have this problem. I will now have to wait till next week to hear from Vodacom. By then Game gave my stock to someone else nd then I have to wait again for stock. I am so frustrated.
