Purchased a treadmill from academy sports and ordered the delivery and assembly package from assemblers inc. I never received my purchase. Called multiple times with no resolution. They told me everything was in the works and yet nothing was ever delivered. What was supposed to be delivered in a few days turned into 2 weeks of me calling and getting no solid answers. It's been a nearly a month since my original purchase and I'm still trying to get my money back.
