You've only recently started selling and as a new seller, payments are usually on hold for 30 days.

Are you actually signed up for managed payments  with verification of your bank account ?

Nothing to do with ebay, sort it out at the bank. nb update your ebay bank info

I am not sure how it went to the 'wrong' account

eBay can only pay into the account given by the account holder

Is it your bank account linked to your eBay account?

Did you change accounts without updating in eBay?

I believe only eBay can help you with this.

Go to "Help" on any eBay page & scroll down to "Contact Us".
