NetFlorist website lies about day of delivery

My mom injured herself on Saturday morning, and I went on to NetFlorist's website to order her some flowers for delivery to try and cheer her up. On the website it said that the bouquet I selected would still be delivered that same day. At check out, it said same day delivery. After payment, my statement said same day delivery. Then maybe 10 minutes after I had paid I get an email saying they could no longer do same day delivery and they would contact me to explain. It is now Monday morning and I have not yet heard a word from them! Unable to get through to their call centre all weekend, no reply to the email I sent. And my mom has yet to receive her flowers. If same day delivery was not possible they should have said that up front, not after taking my money under false pretences! ********* and terrible customer service.
