Question for anyone who has purchased parts from moderndaymuscle.com...how the heck do you go about doing an exchange? I accidentally ordered the wrong end spoiler piece and need to exchange it...tried emailing the site several times, but no response. I don't think my email account is interfering with them responding, because I got emails regarding my actual order with no problem. Do I just pack it back up, send it back with a note saying what I want to exchange it for, and include return shipping? I gotta do something soon, because my 14-day exchange period is going to be up soon!
