I purchased an M3 Simply and one week after receiving it the micro SD card will not seat properly into the unit. It keeps ejecting the card each time I try to insert it. I e-mailed the manufacturer via a link on their website and it's been over 3 weeks with no reply. Has anybody else had this problem and fixed it or has anybody gotten any recourse from the manufacturer? I purchased from ebay through Paypal via my Platinum American Express card with Buyer's Protection. Is this my only recourse?
