Invalid discount codes for product registration

I just found out that the 10% discount code emailed to you during product registration (Via Garmin Express) is not valid in the country. How is that for false advertising. I bet our consumer rights are being violated here. Garmin needs to fix this discrepancy. I am not a happy customer. <br> <br> Serial Number: 24V002589 <br> Nuvi 2360<br>
