Khadim's — purchased shoe..damaged

My family is a customer of khadims, Thiruvananthapuram, Kerala from 2006.my mobile number is [protected].u can check my purchases.i bought nothing from any other shop than khadims in these years.but the shoe I bought on 19.1 2019 through bill no 6038INV009985_18 for price 1299 got damaged within one month.one sole got fully damaged.it was bought on discount and it actual price was double.but I couldn't take up the issue with khadims as the bill was missed from me.i approached mr.pradeep, manager by March itself, of the shop whom I know for several years as a customer.but the purchase date couldn't trace from the computer in ur shop.but today I came there for onethr purchase and I got a copy of the purchase bill.Even though I purchased the shoe on discount which is having genuine leather I expected I can use it for atleast one year.the salesman there also guaranteed it.the amount I expented was obtained by me by working hard and it has that much value.even though it is on discount u can't compromise the quality.or can't cell a product which last only for one or two months for Rs.1299/.So kindly take steps to replace it with a new one.at the earliest .Yours faithfully.H.Najeeb.Joint secretary to govt., general education department, govt.secretariat.thiruvananthapuram, Kerala
