Reliance Trends — Incorrect Exchange Policy

Hello,
We went to the store and availed the INR 3999 on 3999 offer running in the trends, Kolkata. The product of Rs-2799 & Rs-1799 we bought ran size small. So we went to exchange we didn't find the same. So we went for other brands particating in the same offer. We selected the product of Rs-1785 & Rs-1999. The executive on the return desk informed us that rates per product should be exact of the item we want to exchange or you can opt for the credit note of the value priced in the bill that is Rs-1424.78 & Rs-915.73 . He was not ready to take the sum up of 2 products and pay only the exceeding amount if any. It is not practically possible for the customer to see the rate tags and accordingly select the item as it consumes lot of time and infact the look of the product type also matters. Consumer can not choose any random product just to match the rate tags. Further they said the system doesn't allow or accept different amount on price tags, it should be same on the product we bought and that of we wanted to exchange.
