Unhappy customer - Order note complete

So I have used NetFlorist in the past and had limited to no issues. I placed an order last week in advance for Valentine's day only to have a portion of the order delivered to the recipient.

When I has asked why I got a response stating that they don't have stock. So in that case I asked for a refund for the portion they don't have stock of just to be told they can't.

I'd hope they could at least pass credit for something I paid for but no. Not happy at all.
