I want close only my zoho recruit´s account,

I´m Adriana Hernandez, I work at Gonet and we have Zoho Recruit´s enterprise account. The admin is been trying add my user but he can´t. The issue is

"the user already exist".

I have recruit account zoho's (free version), I want close only my zoho recruit´s account, because I need join to Gonet´s enterprise account. (I have others zoho´s accounts, but, them it's ok).
