CashNowOffer review: no answer or contact back to me 1

I sent in over 30 boxes of test strips and not getting any response now from the company... I need that money to buy insulin, I was told that I would get a email back with a shipping or tracking number on it to track my check and payment now I haven't gotten anything and I'm not getting a response by calling or emailing... I cannot afford to not get paid or at least get my supplies back
