Ferns N Petals — product delivered

I placed an order for some customised items and as per them i was suppose to get the delivery the next day but their delivery partner falsely claimed calling me many a times and then when i tried to contact him i got no response, i called the delivery person some 30-40 odd times but in vain. Then i contacted their customer care and they too left me hanging saying that not to worry it will be delivered soon but not sure as it can take a day or two.
My package which was supposedly out for delivery is untraceable and am getting vague or more like no response from their end.
I tried fnp for the first time and am just regretting the moment when i decide to opt for their services.
Need help.
