Advertising stock is available and then refunding the client afterwards and sending random colours!!

Horrible service, ordered two pairs of shoes on 23 Dec and two days later received an email saying they were going to refund me for the one pair because they couldn't find a suitable pair. Why advertise something not in stock? Anyways I made peace with it and collected my pair that arrived at the collection point today. I get home and it's the wrong colour. Does nobody check the items before sending it. You absolutely wasted my time and I'm put off with the bash app. I will rather stick to Superbalist and Zando. Wouldn't recommend Bash to anyone!
