eBay do from time to time, make security checks to see if the genuine owner has returned to sell especially, if some high value items sold suddenly appear amongst some low priced items. Do you have tracking to show delivery for that item?
If the payout is not available in the next day or so, you can if you wish contact CS give them the tracking and see if they can release the payout sooner. Contact CS only first thing on a weekday morning at 8 a.m. this is when ' live agents' start and at that time there's more chance of Dublin answering.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.
