Ynot Technologies Valasaravakkam — Incorrect information about pricing and deducting

Address: Chennai, Tamil Nadu

I am very much disappointed currently with www.100bestbuy.com
I was asked to pay money online for a contest which anyhow gets redeemed as "Credits" if I dont win the contest. Through this credits I can shop anything with that amount as per the site.
But after shopping they show value of my purchase more than that which they had shown lastly before deducting.
This is case of clear cut customer cheating and befooling them.
I can provide further details.
I request you to proceed and do justice to customers like me.
