Reliance Trends — is it the way to fool customer!! invalid coupen code showing with reliance trends.com

Address: 380008

On purchase of 12044 rs @reliance trends in alphaone mall (Ahmedabad one mall)-ahmedabad city, we eceived total 3 vouchers of rs 9000 in which 3 coupen of rs 1000 is included. So when we try to redeemed 1000 rs coupen on www.relianvetrends.com it shows incorrect coupen code & for every 3 coupen of 1000 rs each has mentioned same "use code"...
Is it the way to fool customer???
Is there any help or favour reliance can do on this issue???
Pls find attached bill and coupens snap for ref...
