Mint Newspaper — newspaper coupons wrongly delivered

Address:

Mumbai City, Maharashtra, 400071

I gave a cheque for annual subscription to one mr premsingh for mint newspaper. The amount was rs.1398. The coupons were wrongly delivered at someone else's house. Now staff of mint is claiming that they gave the coupons to some lady called kamala. My father is 91 years old. My mother is 84 years old. We are an ordinary middle class family. I cannot afford to forget the amount i have paid. Please help.
