Ferns N Petals — pathetic service and response, wrong delivery commitment

My order i'd :14930621
I had placed a an order on feb 5th, and they had shown that it will be delivered on feb 10th, and i didn't receive it by that time, so i immediately contacted them as i need before feb 12th, as am leaving from my place (Visakhapatnam) and no one will be available to collect it, and that's the reason i had placed order very early to the occasion and i informed them the same, they said they will inform it to the courier team to deliver as soon as possible. Again after that i did not receive any information from them regarding my order delivery, so i contacted them again, and this time they said that it's not their work regarding the delivery of the courier.! I got pissed off with them and asked for an proper status of my order, they said they will but they didn't.!
Again feb 11th, after contacting them several times, and then they responded that they will try to deliver on feb 12th before 8pm, i informed them that no one will be available at my place after 12pm, they said it's not possible, so i asked for an address change and they gave me commitment that they will deliver to bangalore on feb 14th.! Today me after reaching bangalore i got a message that my order got delivered to some random person at visakhapatnam without contacting me before delivering it.!
How can they be so irresponsible without contacting the actual recipient, how can they deliver it to some random person? I asked them the same and they said the courier people won't contact like that we don't know! Such a pathetic response,!!! If that's the case then why did they hire those courier people in ferns nd petals.?
Aren't they responsible to deliver it to the right recipient when i ordered through ferns nd petals even after informing them several times that no will be available after that particular time.!
Either i need my money refunded back or i want my order to my updated address, please do help.!
