Cashback kart and trendydeals

I have ordered oppo power bank costing rs. 899two days before on cod. Yesterday eve i received email offering discount of rs. 100 and asking me to pay rs 799 within two hours to avail the discount. I did it through icici netbanking amount transferred to trendy deals which has acknowledged my money. But when i tried the store it is not opening and i sent three mails giving full details and requesting to furnish the details of despatch of product but all mails bounced back k and the mobile numbers what they give is non working numbers. This seems to be fake. I requested the bank to close my debit card and other banking activities to avoid any mischievous activities. I want money back and close such fake websites
