Ring Doorbell 2 detachment from account

Hello, i was using my doorbell 2 normally from the app on my iphone and after a time i was wondering why i dont receive any notifications and i saw that on the app it said to put again my email and password. i wrote them and it said that it is wrong. After that i tried to reset the password and succesfully i make that. i logged it to my account and no devices was associated with my account. I make a reset to the RING Device so i can install it again and of course it said that the device is registered to some other email (user). i check all my email and spam folders and i didnt find something. Now the device is useless . i tried to contact RING but their telephone support doesnt work due to Corona-Crise. Any help would be nice. Thanks in Advanced
