Every single seller who has not sold in some time will have a 30 day hold on funds. eBay sees you as a 'new seller'

It does not matter how long the person has been using eBay

You agreed to the policy when you listed the item and ticked you had 'read and understood' box. so if you think it is 'not right' yo did not have to proceed with the listing

Your last feedback as a seller shows 'more than a year ago'

The holds are not new and are no secret 

And yes, sellers do need to supply the item within their stated handling time

Contacting eBay is not going to get you special treatment 

Have you indeed signed up to Managed Payments and been verified to sell?
