Have I been scammed?

Description

Hi there, I sold an item on gumtree and used paypal to receive the funds totalling £330 (the guy seemed legit using whatsapp to communicate with me) I got sent some emails from however I noticed that it had another email with it from (had to put spaces in between so post could be allowed)saying my payment is on home as PayPal need to do an limit upgrade on my account? Have I been scammed of my product I sold and the funds coming to me or am I being paranoid? Please help me! Kai
