I want to delete my primary account erick@siziki.com ... My coworker is the owner of that domain, he sent me an invitation to my mail ( erick@erickdev.com), I don't know how I associated that account as my primary account as that account doesn't exist. When I try to change or delete any of my other accounts it ( erick@sikizi.com ), zoho says that it is not possible as I haven't confirmed my main mail, but I will not be able to confirm it because erick@sikizi.com is not a valid mail... 

I would like to convert the account erick@erickdev.com my main mail and delete erick@sikizi.com. I don't think that as a user I'll be able to do that, I will need somebody from support to do it.
