Im very sorry for your trouble, I understand loosing your contacts is very frustrating!
ShuttleCloud is specialized in contact and email migration, that is, we are the platform that transfer contacts and/or emails from one email account to another. Nevertheless, we do not have access to any of your accounts or keep any personal information saved or stored, Im very sorry we cannot help you any further with this issue! I would suggest you contact Google Support as maybe you kept copies of your contacts in Google Drive.
Please let us know if you have any doubt concerning email or contact migration and we will be happy to help!
