I ordered flowers to be delivered to my friends in Durham, GB, to celebrate their wedding, on the date and specific time guaranteed by the Serenata website. I paid a ridiculous amount of money for it, including the specific delivery window. I never received the notification of delivery made, so I tracked the order and discovered it was still being prepared 5 hours later. That wasn't acceptable, as my friends weren't going to be at that address later. I filled a complaint form on the site and got bombarded with compulsive emails next morning (time zone difference) making apologies and excuses but refusing to cancel the order and refund for the now-useless flowers. They just wouldn't stop with the emails. It got ridiculous when they proudly shoved their TOS at me, explaining their liability and lack thereof, and it became clear that not only they don't know the meaning of the word "guarantee, " they also don't know the meaning of the word "liability" (vs. "refund"). I don't recommend dealing with them at all.
