These are MD8049. I explained the issues with them when I finally got through for the RMA number. Invoice 14003275. You received them back on 11/18 I believe. I received the refund today via a PayPal resolution in my favor. Would be nice if you just issued the refund when you receive the product instead of making a customer jump through hoops to get it. As for DMT, at $1.25 each versus $1.95 each for yours, these work perfectly and look nicer. DMT number. CHR6001798. Thanks!
