Dear sir,
I had purchased worth10k at trends they give me footwear coupans worth 4k and it will be valid till 27 jan. And today we went to buy footwears the staff said sorry sir we dont have stock. I mean what the hell... I[censored] dont have proper stocks why did uh provide coupans worth 4k..?
Requesting uh to kindly resolve... And i need justice.. Am feeling like trends had played game with customers...
