H1b revoked and B1 also revoked with it with no reason

Hi, I recently travelled to US on H1. At port of entry I was returned back and my H1 as well as B1 was revoked. Reason being a bond with my previous employer who filed for H1.

Is revoking B1 wrong in this case as it wasn’t with the same employer as my H1? Also, what are my prospects in future?

It’s the officer’s discretion. You may do nothing about it. Try applying again if you wish to.
