All new sellers have a listing restriction.
Have you added a credit/debit card to your account for eBay fee's ? That will somtimes make requesting higher selling limits acceptable.
Basically, eBay are wanting you to prove yourself as a seller before they allow you to list larger amounts.
You can call them

but usually, it just takes a while to build up a reputation.
