The Ordered Date was Date: **-**-**** . They took more time to supply my ordered plants to my address in Kerala. they delivered plants via Truck on **-**-****. I paid Advance amount of Rs. * Lakh on **-**-**** and they prepared final Bill on **-**-****. They send me the plants photos before ordering and I was satisfied with the product after seeing the photos. Then I confirmed order. But at the time of delivery , i found that the supplied plants are different in variety and also **% of plants are damaged. i contacted the supplier but he is saying that this product only he had in stock and he cannot supply the products which he shown in photos already before. As a farmer it is very disappointing and I lost my valuable money . Please assist me with any legal support if Possible.
