Gmail account restoring old address

Help! this is a complete ambush. Lost phone contacts. Not all, but recently. Synchronization of contacts has not been done for a long time. On the phone, all contacts were saved in a google account. and I needed to format my phone, and I was worried about contacts. One of the options to view contacts through a computer was using the Google Mail (Gmail) mailbox. At the entrance it was necessary to indicate the address. The current one did not fit, I indicated another. and after that, the account address changed in the phone, keeping only the old numbers at the last synchronization. Is it possible in this case to return the lost numbers? or old account address?
