navdvdmaps.com carpcstuff.com Navigation DVD doesn't work Internet

 I ordered a navigation dvd for a 2009 Scion XB. To their credit, the DVD arrived very quickly, however, it didn't work in my car. I immediately tried to contact them, only to find a "contact form" was the only means to communicate with them. I submitted the form and waited for a reply, I resent the form again 5 days later. After trying multiple times to contact them with no response, I submitted a chargeback claim with my credit card company. 3 days later I received this response from them. They still haven't addressed the issue that the DVD doesn't work, but they are now trying to intimidate me with threats of "penalties." Their reply-

************* We received a Chargeback Dispute from your bank regarding this order. Our response procedures and fraud prevention steps have been followed by providing the order details, your IP address, and confirmed delivery information on 3/2/2016. To avoid any penalties for making fraudulent Chargeback Dispute claims we suggest you contact your bank and inform them of your mistake. Regards, Customer Service *****************

The ironic fact is, that I explained to the credit card company that I did in fact receive the disc, but it didn't work, so they simply confirmed what I had already told the credit card company!! Thanks guys!! I have since purchased this DVD elsewhere and it works great, so why couldn't they simply respond to my original requests to correct this problem without having to resort to chargebacks?? It should also be noted that the DVD that was sent, appears to be a blank disc that was burned from a copy of an original DVD. The disc that was sent has a sticker on it with no copyright insignia listed, so I suspect it is a fake, pirated copy, however, I cannot prove that. They very well may have an agreement with the original copyright holder. All I can confirm, is that is doesn't look like the 2nd DVD I purchased from the dealership.
