Reliance Trends — Coupon fraud

Address:

Vellore

Hi we shopped in vellore reliance trends for around 20000 in January and 12000 last month. So last month they gave us coupons which should be active from March 8th ie today, out of 10 coupons that we got only 2 are redeemable
Remaining 8 coupons it’s showing coupon not activated, which implies while billing us they forgot to activate our coupons . Very much disappointed being a high valuable customer
