Indiatimes Shopping

non delivery of product, even after the payment was made
Hi, I made a purchase via an online shopping from Indiatimes Shopping, using an HDFC Bank discount voucher (Coupon code - SR210113K1A1Q1QDCMUP7) on 26th of March 2013 for which the order ID is 3002153216. The payment was made through Net banking of HDFC Bank. Initially, the people at Indiatimes shopping told me that they have not received the payment(Case ID: 777209), but after 10 days of the purchase, they informed me that the payment has been received. Now, after that a person from Indiatimes called me and told me that the discount coupon I used was invalid, though the coupon was valid till 31st March 2013 and also told me that I will not have to call them again and again, they themselves will call me and update. They gave me a new Case ID(789276) on the 6th of March 2013 and since then, I've not received any update or information from them.
