Possibly the worst customer service ever!

Possibly the worst customer service ever!
I was advised the product was in stock via the website and had been dispatched, it never arrived.
Then I was advised there was a problem processing the order as the warehouse was not showing stock when their was actual stock?!
This went back and forward via email until I called and eventually got my item sent out.
However sizing is very small so this was returned . Like ordering the process for a refund is ridiculous, I was sent an email advising they had received your return , then 6 days later I received another email to say my refund will take another 10 to 7 working days
