First of all the quality of the product (shoe rack) was really poor. Very low grade and inferior quality of engineering wood or MDF were used. And once the product was delivered there was no option to return it and hence was forced to use it in spite of the low-grade material. Within * weeks of use, the side panel (joined with the main door panel by * thin wooden sticks and not even some proper screw) came out causing the entire door to get dismantled. On raising the complaint to pepper fry they simply ruled it as damage due to usage and regular wear and tear and denied me any repairing service under warranty. It is a shoe rack and am I not supposed to use it by opening or closing the door?
And how did they ascertain it? It was decided by some case manager just by looking at a single picture which I had uploaded to their app. How could they ascertain that without even inspecting it physically and simply checking the picture when they might not be having any expertise in manufacturing or assembling furniture? How can they ascertain that the section didn't get damaged while it was being assembled by their carpenter? In spite of raising the issue with them multiple times, I was told that the product won't be repaired by them. The panels came out clearly because of the damaged poor quality of the wooden pieces used to join the sections. It could have been as well delivered to me like that and there was no way of knowing that. I need PepperFry to address this issue. This way they are harassing customers and simply denying warranty to them.
