BestBuyFragrance.com Shipped half the order, claim to have shipped all Internet, Internet

I ordered two bottles of perfume.  The package arrived with only one bottle.  I notified them and they are saying I am lying and I need to file a police report.  Here is their response:

Thank you for contacting us with your issue. I have reviewed the shipping receipt for this order with all the shipping details. To prevent shipping mistakes such as this, we have several employees go through the process of printing the invoice, pulling the products, packing, verifying, sealing and weighing the package before printing the shipping label. Typically one item will weigh .13 oz up to 1.3lbs, depending on the product. This package when shipped weighed 2.5 lbs. You should also be able to see the package weight by viewing the shipping label on the box. Also on the day your order was shipped, due to our slow season, there was only 6 orders that cleared to process this day. The representatives who packaged your order and sealed your order, both separately noted the same details and information for your order number. With this in mind, if you did not receive both your products, you must file a police report and also a report with your local post office as your package was illegally opened and your products were indeed stolen. If we can be of further assistance, please feel free to contact us for further information. Thank you.

Sincerely,

Farrah Z.

I emailed them back stating they need to check their inventory, otherwise, I would be filing a claim with my credit card company.  I have been ordering online for over 15 years and have never had a company accuse me of lying about product received.  This is unbeleivable.  I also found many other complaints about this company after I received this response.  They are unethical and I would never order from them again!
