For Online Computer Support, Ask a Computer Technician
i can try with you. it will depend on a few things.
1. if you have the passwords for the accounts
2. if you actually deleted the account or just removed it from the mac
3. If you linked them together at gmail or had other accounts linked to them
4. How long ago it happened
I would suggest that if you want to pay for additional service i can get you my phone number and log into your computer remotely to work together to get it fixed.
