Changing Account Credential Data

Probably one of the worst problems with blynk.
If a user gets his email account deleted, deactivated or simply loses with access to it; how is a user supposed to change his credentials?
I’m actually in such condition since the begging of this year. Support or bot says it will pass to someone responsible. Yet, after almost a year I still can’t do anything about it nor have received any support.
I wish to add power to my Blynk account; I don’t want to pay for what I’ve purchased again… This is not wise.

Thank you or understanding.
