Reliance Trends — server not working for coupon redemption

Address:

Kurnool, Andhra Pradesh, 518360

I purchased for above 3k in trends of yemmiganur branch, kurnool district. They said that if i purchase above 3k i'll get 2 coupons for rs.500 off on purchase of rs.1000 each. And the coupon is valid upto dec 5, 2018. Now when i went to trends they replied "the server for coupon redemption is not working, not only this one store but also in every store in india". There is only one day left for coupon validation.
Suggesting for getting the server back soon.
