Reliance Trends — staff refused to accept gift voucher

Address:

751023

Hi,
I got a gift from my colleague as reliance trends gift voucher worth of rs. 500. Today i went to store at bhubaneswar patia, where staff refused me to avail the voucher. I asked why, he seems confused and called somebody about the acceptance of gift voucher.
At the end he said that we are not accepting this kind of gift voucher now because of some issue and didn't gave any valid reason for not accepting the gift voucher.
Kindly help with this.
Regards,
Pradeep
