Almost Lost My Google Account (Click for more info)

MM made me remove my email/phone recovery options(usual procedure), then MM changed the password of my google account but did not make me put his recovery mail/phone (so when MM changed the password, the recovery options "mail/phone" of my google account were left empty/blank).

After that Google preventively locked the account (something usual that happens 99% of the times a new ip/device changes a password) but this time recovery options (mail/phone) were in blank/empty

This led to an imposible recovery bucle, where google as last question to verify "its me" always asked me for a code sended via gmail to the same email im trying to recovery, making imposible for me to recover my account even when my device was familiar and was loged for more than 30 days with the account.

Seeing this, as last resort i tried to recovery my google account with an unfamiliar device and this time google to verify "its me" as last question asked me for a code sended via gmail to an email that belongs to the previous owner before me.

So i was at the mercy and good will of the previous owner to recovery my account.

In the end after some days waiting(depressed in the meantime by not knowing if i would recover my account) for an answer/help of previous owner, i managed to recover my account.

But this mistake (change a Google Account password with the recovery mail/phone left empty/in blank) almost made me loose my account, my investment and a potential sell.
