Worst customer experience ever

Worst customer experience ever after an online purchase. Purchased an air fryer online. 10 days later after not being able to track my order online, I try to phone the customer care number...just rings...I was on hold for nearly an hour, and no answer. I tried the chat option online, but *********** staff on the other line that can't give me answers on my order. I eventually get an email to say the air fryer I purchased is out of stock, do I want a refund to which I reply yes. It's been 2 days with no response and the number on the email doesn't exist and the online chat still tells me my order will arrive this week. How does this make sense? I have sent numerous emails to all the channels, and still no response from Incredible Connection.
