Ajio — redemption of coupons

We were in chennai in the month of june 2019, we went to reliance trends and did a purchase for an amount of 10, 000 rupees, while paying, they said we will be given coupons both online and also coupons which can be redeemed at any reliance store in the whole country, we had 3000 rupees worth of online coupons and also 3000 rupees worth of coupons which can be redeemed at any reliance store directly, but it is very bad on the part of these stores that they failed to accept these coupons at a store saying that they will only be accepted at chennai, is this fair from reliance trends??? And also i tried to purchase online so that i can atleast use my online coupons, but that website trends. Ajio.com is a complete waste of time and energy, we look for items and finally when we want to purchase to redeem our coupon, it says, “the requested url is rejected”, i really don’t know what the hell is wrong, so i have sent an email along with screenshot i was seeing to the customer care team, they came back saying it is ajio team who should look into this, i tried to explain them the same again and again, they just ask me to check my browser and all, not at all responsible for the customer’s intentions and they just give fake coupons which can never be redeemed,, i want my 6000 rupees back now!!!
