As a new seller you were given restrictions on the number and value of the items you offer for sale.
You can ask every 30 days for the restrictions to be dropped but until you've been selling for 90 days and sold 25 items your payments will be held until tracking shows delivered, or in 21 days if there's no tracking.
They can hold the payment for the full 21 days if you're selling in a high risk category.
High risk can mean high value or high fraud.
Check the value/number you were given by eBay.
Often it is as little as 100items/$100 .
Which means you could list 100 items for $1 each or one item for $100.
But not 100 items for $100 each.
Supply the documents as well as you can. On older items, it is to be expected that you don't have receipts, just do your best.
Remember you are dealing with a robot.
If you need help try the eBay employees assigned to the social media accounts. They are better trained and have some authority unlike the phone clerks.
But at this point, nothing unusual is happening.
The US government and eBay are cracking down on possible stolen merchandise online and you just got caught up in the investigations.
It's nothing personal.
