Girias India Investment — Delivered the Display piece which was a like a used one - Whirlpool 340L

I have bought the Whirlpool fridge(340L) from GIRIAS on 02 Jul'22 at Karur. After the full payment it was confirmed over the phone that they will send the fresh piece from the warehouse(godown) but still they delivered the displayed piece which was like a used one. During the Demo we got to know that this was the displayed one. So we approached and after a long discussion they accepted finally and agreed to replace with a brand new one. Still that has not happened after 10 days and now the sales person speaks differently and bit rudely. Saying like you listen to us first and there is no hard rule that we should not send the display piece and all.
