Reliance Trends — store guys denying for the offer after telling that the offer exists

Address:

Offer - 2000 off on purchase of 4000. My friends got the offer and the store guy and the billing counter guys too told me that the offer exists. After spending 2 hours in the store and picking up the murchandise when i go to the billing counter the store manager denies to give me the offer. That was so inconvinient and unfair on your part to do that. Kindly consider this and give the response.
