NurseryLive — non receipt of the product

I had ordered the product on 26th feb and till today i have not received the product. The customer dont respond unless i tagged then on facebook and then i was asssured that i shall receive the product next day but that too has not been received. I want to cancel my order and want my money refunded. Its been more then 10 days and no status till date. The courier status is also not updated since last 6 days and i am not sure how plants will survive in more than 10 days courier (Till date, i dont know how many more days will it take them to reach).
