NurseryLive — Ordered Sterculia Urens, they sent Castor Seed

I ordered Sterculia Urens, 2500 rupees worth, seeds from them, they sent me 50 rupees worth of 1 kg Castor Seeds. This is calculated fraud and doesn't look like a mistake. I have sent them 10 emails in very polite terms and they haven't responded to the mail. This is a major scam from such a big plant seller with all their apps and website. They continue to send me emails about their products but did't respond to the complaint.
