Request a Refund:
Seems you've been scammed, though a full assumption on my part. So, ask this person for a refund. This is the site they should have used: What to do Before you Sell, Give Away, or Trade in your iPhone, iPad, or iPod touch - Apple Support. The seller should have known better.

Next time you go about purchasing a device from someone, request that they let you log into your own iCloud account on it, prior to handing over the money. If they decide to disabled by those rules you've set forth, then do not proceed with the transaction.
