I just got registered on paypal, bank account details cleared etc....great

So I go and buy something on ebay, send payment, get receipt off paypal...then paypal send the guy Ive sent payment too telling him not to send item as their was a problem.

I go into my recent activity on paypal and it sais Payment: Uncleared

Why?

it sais something about waiting 7-9 days?

Is it just because im a new user or is their something i've done wrong?
