I can't delete my account and they do not have a phone support, the emails I sent (several) they don't even answer because they say is not associated with my account. I feel I have no rights of my own privacy. They say I have to contact the email provider. But I don't have this email for years. They don't find another way to verify if it is me. Someone help me I don't know what to do!
