Pepperfry — wooden cot - broke after 3rd use

The cot is just three months old, and day before yesterday it was my third day sleeping on the cot since we kept it for guest room, since we have a different cot for us.
The cot broke in middle of the night. Luckily i didnt get hurt.
When i contacted your customer care and raised a complaint, they closed it telling it is wear and tear issue. So they cannot replace or repair it.
Their customer team agreed the product is not up to the mark and suggested not to buy any furniture from online.
But as per the policy they says warranty is 36 months for manufacturing defect, this is just cheating.. How can they say warranty of 36 months for manufacturing defect.
They are just cheating customers. Please look into the issue.
