Poor service delivery

Ordered a birthday gift on the 19th of May for delivery on the 27th of May. Order has still not been delivered and Netflorist is distancing itself from the late (rather no) delivery, saying the issue is with a 3rd party. I had to call them on the 27 around 1pm to follow uo on the order, only to be told that it was delivered at the 3rd party's port on Tuedsay, the 26th of May, and would be delivered on the 27th. Called today, the 28th,and was told that it arrived at the 3rd party's port on the 27th :(. No prior communication from them or the supposed 3rd party (via sms or email or even phonecall) regarding the delay.
