prize redeeming

I still don't understand why a big and reputable company runs a competition that is so unfair.Do you honestly expect any customer would keep a receipt for a juice to redeem a price?Its not even stated on your competition rules and regulations,making the entire promotion run unfair.The way it is being handled by the participating stores it leaves so much room for litigation,which I am considering.I have spent money to go and claim my prize in vain due to false adverti*****t on the promo or incompetence of those stores.I did not only spend money for transport,but airtime to claim the prize and time I can never regain.I expect a response to my complain soon<br> <br> Ivan
