Detach profile from BEP for H1B visa

Hi I got my Visa through MNC in India. Now i"m seperated from the company (got Visa transferred)and planning to take up new stamping. When I try to register new profile its not allowing me as its duplicate of earlier one. When I contacted my ex-company BEP coordinator, he say he has no idea on detaching the profile.

Can someone tell me the process to detach the profile from Company BEP
