Netflorist website woes

Ordering from netflorist was such a nightmare for me.... Tried multiple browsers, different computers and have programming knowledge, yet I spent 3.5 hours trying to purchase the items I had selected in the first 20 mins... 10 items in the cart, the site lost the items in the cart 6 times! 3 of the 10 items I would search for and the site will just hang... Spent all the time having to re-add the items. Site was terribly slow... So slow in fact that from starting at 9:30am, I missed the first item delivery for 10:30 cutoff and the 12pm cut off... The online support apologised and made me clear some things from my side and start again from scratch (didn't help anything) , the telephonic support argued that I didn't have anything added to cart despite me looking at the cart on my pc at the time. Started again from scratch... 2nd telephonic support at least informed technical department... But I had to start again from scratch... Struggled a few more times... Eventually added product in some correct mythical order that allowed me to get to checkout... Only to have dates no earlier than end of december despite it saying same day or tomorrow delivery... Pull out of checkout and cart lost items again! This time followed some mythical order and finalised payment.. All fingers crossed that the delivery runs directly opposite to how site is working...
