ApplianceZone.Com sent wrong part , no way to make contact with a rep Internet

I purchased a facade insert for my maytag refrigerator.  It took 17 days to arrive and when it did it was the wrong part. I gave the company the part number supplied by maytag and they sent a completely different part with a different number. When i tried to contact the company for a return there is not contact number.  You have to sent a from via email. The paperwork have no address for the company and has no contact numbers. Invoice is very vague.  I contacted my credit card company and obtained telephone number for the company, 812-225-5318.  The credit card company has the letters in after the number, which may mean the company is in Indiana.  If the company fails to make good, I plan to see what Federal Agency Investigates this type of fraud. I also plan to have the credit card company stop payment or deduct the amount from the company's account.
