Rejecting a purchase on an order?

Rejecting a purchase on an order?

So what does rejecting a purchase do? Does the seller have to re-do the thing you have purchased if given a good enough reason?

I recently purchased 500 subscribers, and on the page it stated in bold, red font that 70% of the subscribers would have over 5 subs themselves, and 50% would have over 200 subscriptions. They have now said the purchase is complete, and though I got the 500 subs, only %5-10 of them are over 5, and only %1-5 are over 200 subs. Is this enough to request rejecting the order?
