I lost my phone with the app while escaping Venezuela 8 years ago.
I have my email, password, and even the phone number to deactivate 2FA, but I get this message: The Nexmo platform could not process this message for the following reason... (it doesn't actually give any reason)
This is a major problem to be encountered on this site that already struggling on maintaining their customer relationship through live support.
Having all the info that you mention is not enough to recover your account. You need to verify it with some details like last transaction, wallet address that you use to deposit and so on.
But the problem is still the support is very hard to reach these days.
