Bikers Den Ordered a leather vest and gloves. I received the vest but the gloves never came after 5 months. Will not return calls or emails. Oregon

After five months of emails and phone calls still waiting for the other half of my order from Bikers Den.  No matter when you call you must leave a voice message providing them a return tel number. I never have received a return call and no answers to my emails.  The shipped item arrived in a regular usps box with no paperwork.  No promised tracking number was provided.  I recently wrote Bikers Den to be given instructions to return the half order I now have.  Still have heard nothing.  I will be contacting BBB and my Credit Card for investigation.
