Item is fine but, failed to refund me! Entity un-contactable.

purchase a server case, The product arrived in order, quick as well. I returned it a day or two later by post after receiving no answer to phone calls and emails. Returned the item in accordance with their returns policy on the website. Over 2 weeks later, i have not been contacted, refunded and they still do not answer the phone or respond to emails. I wont be dealing with this entity again and would not recommend using them.
