Avoid sportsmans warehouse like the plague

Ordered shoes and supplements online. Received a message to say it was despatched. Shortly after received an email saying the shoes were no longer in stock. And they will refund me but the rest is still on the way. Then got an email to say they accidentally made out a refund for the full amount. Asked for my banking details. It is now almost another week later. No refund. No response. From what I have read this isn't the first time this has happened. This is blatant theft from their side. Terrible terrible service.
