regardless if he sends the tunes today or not, you should still report him to the BBB. issues like this usually get undocumented because the buyer (you) is just finally happy to have what they paid for that they seek not any further action against the buyer other than to never shop there again. This is good for the buyer, but not other buyers. hope it all turns out for you in the end.
if it were me i would still send it back and report it. because if you were to need a new tune you would have to go thru the bs again
http://centralflorida.bbb.org/ go to this website and from there you can file a complaint or whatever else you want to do. VMP is out of Deltona Florida, which is central florida. good luck bro!
