These dudes are not business friendly. A artist known as Sapp Reefa from www.sappreefa.com had recently started doing business with mixtapeslots.com. The deal was they were suppose to promote his mixtape around this clock. At first everything was going smoothly until all of his views, downloads, ratings, and comments just disappeared and started over. Sapp had no way of contacting them so he did what he knew would get there attention and that was to go through paypal and stop the comment to this issue was resolved.instead of them working out a resolution to restore the views, comments, etc. They chose to give him a full refund but behind it they sabotage his mixtape to get him kicked off of datpiff.com by running up his numbers so fast to make him look like a fraud to the site and also started posting all types of negative comments and if you don't believe me check out this link (Content Removed)
The same people that are disrespecting sapp has found his mixtape on datpiff several times and has got him kicked off the site. Do not do any business with mixtapesnot.com they are losers not real business men.
