Nothing to do with selling before or how long you have had your account

You need to actually read what you ticked you had read and understood when you listed

other members cannot help when you ignore the actual questions asked in order to try to help you

Managed Payments is for ALL sellers, including you

How long you have had an account and how much you sold years ago is not relevant 

ebay consider you a new seller, as they do every seller who has not sold in some time

Even if you DID complete ALL steps for Managed Payments AND were confirmed as verified, the hold is STILL 30 days

If you did not complete everything, you do not get your money

It really is that simple
