How to unmerge Verizon One ID accounts

I need to unmerge my Fios and wireless accounts. Currently my mobile account is linked to an old deactivated Fios account from years ago. I can't merge my current Fios with my wireless under One Verizon ID because it is still linked to my old Fios. I've called, chatted, and tweeted with both Wireless and Fios agents, and no one can help.
