I can't get anyone to answer my e-mail or tell me why my Platinum rewards are not working.

I can't get anyone to answer my customer service questions and I called already, and was told that my Platinum rewards were not working and they would have someone fix them, however, they still aren't working.  I didn't get them with my first order, and I'm not getting them now when I try to order.  There is a reason why I can't use my rewards (I did purchase over $100.00), and why my Platinum status isn't updating in my account, and why won't anyone contact me or fix the problem?  Please advise.
