Unreliable delivery

I ordered flowers to be delivered on Saturday. Received a phone call on Saturday morning that you do not deliver on a Saturday. (No mention of this on the website). Promised the flowers will be delivered on Monday. The flowers arrived at 5 on Monday afternoon!! This is utterly ridicilous. No mention on the website of this! Nothing. I asked to be notified when the flowers leave the warehouse, so I can plan my day. Also not done! This was the last time I will ever use your service! Very expensive and UNRELIABLE!
