Consumer Redressal

Dear consumerredressal team, This is with reference to my order no. is 23661495 which i had made with 100bestbuy on 21st July-2013 at around 11:30 PM but due to its fitting issue I had mailed them for replacement and asked them that i will purchase somthing for that amount and i sent the order back after confirmation mail from them. I dont remember the date but i have recd the cal from 100bestbuy that I could either be refunded or can purchase for that amount as I could not get any item of my liking at that moment so I agreed for refund and was assured by them on phone that money will be refunded to me within 7-10 days. I had posted several queries at their all ID\'s service@100bestbuy.com; care@100bestbuy.com; info@100bestbuy.com; legal@suksh.com; track@100bestbuy.com; info@100bestbuy.com several times but did not get any favorable response except service mail \"Dear Customer Thank you for you email . Plz chk the tracking FAQ, etc.I tried to cal them many times but unable to conct them
