The policy(ies) are very very clear. no secret and up to you to know about (since you ticked you had 'read and agreed to')

And they are not 'our' policies , we are members like you (being a member to member forum)

Indeed, the hold on funds apply to all new and infrequent sellers, including you

It shows you have no feedback at all on this account, so is there a reason you believe you should be excluded from the same rules as every other seller?

You are lucky it is only three weeks for you, normally it is four weeks

Please do feel free to close your account, eBay do not care and will not notice
