Left me stranded - inconsiderate & poor service

I am so heartbroken. I ordered a stove from their online store. A week later they call me to tell that they do not have stock of the stove. I have scheduled moving into my new apartment around this stove as I cannot afford takeaways. Not only did it take them a week to realize they do not have stock, but I still have not recievwd my refund. The only funds i have left to get myself another stove. I don't even have takeaway budget. They have left me stranded. PLEASE SEND ME MY REFUND
