Grubhub.com suxxx! Charged me for dinner - canceled order - still don't have money back Internet

Ordered and paid for dinner 7:37 PM on July 4.  The site has a function that let's you know when the food will come.  When the actual time passed by the target time (it was 10PM, food was 'going to be there' at 9:25) I called California Pizza Kitchen, which was supposed to receive the order.

THe woman at CPK said no order was ever received, that their kitchen was closed and (in a nice way) that we weren't going to find anyone locally who will deliver the dinner.

Sometime later that night-after I had gone to Wawa for dinner-when it was too late to make any other comparable arrangements, I got a note from Grubhub that my order was canceled and it said i could get $10 off a future order.  Sorry about ruining your entire dinner, here's $10 - and you have to keep doing business with us!

In contract terms, they breached their end of bringing dinner.  Additionally, they did not refund the money yet.  They said it would be 3-5 days depending on MY bank.  

There's no accountability here.  If the site had the functionality to say, "it's a holiday, you can't get dinner delivered,' that would be fair enough.  Note that the local restaurant that we normally use for takeout did just that.  

Equitable fraud is when someone enriches themself while basically stealing from someone.  That's what this is.  Equuitable fraud.  They didn't deliver dinner and they are sitting on my money.  They also prevented us from eating during dinner time.

I am in business and if this is how I treated customers, I would not be.
