Update: Google reviewed our case and reinstated the accounts. I really appreciate your help and I'm extremely grateful to anyone in this community who helped us to reach a real representative in the policy team. Although our issue has been resolved (and we are really happy about that), there should not be a need for such a social media campaign in the first place and not all small businesses might have this chance to reinstate their accounts. I hope that the team at Google stops associating the accounts automatically and would improve their relationship with the developer community more than ever.
