I was supposed to have won a $10 Amazon Gift Certificate, but I have not received it in a week and a half.  I have left several messages, but haven't received any response.  They say that they give away many prizes, but my experience is not good.  I have given them over 10 days.  I decided to erase their software and stopped going to their site.  The least they could have done is respond.

I won $50 on I won and the pop up said it would take about 6 weeks to receive.

Give them time. Prizes are not usually given to you instantly even if the win is an "instant". It takes time for them to process and some companies are a little slow. I'm sure you'll get your prize with a little patience and some time.
