Fevikwik.in / Pidilite Industries — fevikwik dried up

I am a stationery retailer in uttam nagar, delhi. I had bought a 81 pieces packet of rs. 4 each from a wholesaler here in july 2017. Only 15 are sold out but the remaining packets have dried up so please provide me the replacement as the wholesaler is refusing to take it back.
I was a regular buyer of the 12 pieces packet only but then suddenly the wholesaler provided me this option and i also decided of buying 81 pieces at once thinking it was a good deal.
So kindly request you to assist me in this case as 81 is reasonably a big number
