I have ordered online frm www.100bestbuy.com the products as below on 14.05.2013 :- 1. Black casual belt of Rs. 510.00 2. Leather shoes of Rs. 1190.00 3. Laptop bag of Rs. 1780.00 Out of the above 3 products, 1. I have rec. Casual belt on 21.05.13, 2. Leather shoes rec. on 22.05.13, but I returned it (after talking on their helpline No.) same day by courier as it was of different color & style, 3. Laptop bag has not received till now dt. 28.12.13. After follow up on their helpline no. they told that refund of product no 2 & 3 will be credited in my account and I can use 10% of the amount for any new puchase and balance cash I have to pay by credit or debit card. The refund of Rs. 2970.00 is still not credited in my account. I told them many times to refund the money, but they are not taking action and not refunding the said amount. My problem is still not resolved. I request you to take a strict action against this cheating done by www.100bestbuy.com.
