Ordered takeaway from Just-Eat.com and never turned up?

[Carly]

I order at around 3.00 AM, it's now 05.15 AM and it has not yet turned up. I googled the number for the takeaway I ordered from however there was no answer when I rang. I paid by card so 12.50 has been taken from my bank account however I haven't revived the food I ordered.
Is there a number I can ring at this time? As you can imagine, I am angry at the cheek of just-eat/the takeaway I ordered from for taking my money yet not turning up.
There is quite heavy snow in the city I live, however there has been no contact whatsoever informing me that the takeaway has been cancelled and the money has been taken off my card.
What should I do?
