As the details are all different (assuming it's a spouse or kids account?), then there's not much you can do buy wait it out the 90 days. If it was your account you can ring PayPal and ask them to remove the restrictions as you have a good selling history. If they refuse, a complaint lodged with the financial services ombudsman usually sees the restriction removed within a few days.

If the items have arrived and the tracking shows that it has arrived, you can ring PayPal and they will release the funds on those transactions while you are on the phone. If you upload tracking numbers to both eBay AND PayPal, often they will release on their own when they show as being delivered. If not, call them. Otherwise, as mentioned, you have to wait 21 days for the funds to be released.
