Email address change for TwoNav account

Hello everybody!

I have urgent need to change the email address linked to my TwoNav account. I already opened a ticket but after two days I didn't receive any answer.

Since the new email address is still associated to a TwoNav account, I sent the dedicated form according TwoNav FAQ but no answer in this case as well.

Can someone help me to understand to escalate this request to have an answer?

Thank you very much
