I have no idea what the ED voicemail even said or when it was from. At the very least the ED could have posted a clear video of it.
99.9% of my voicemails I have no issue understanding. It is very possible neither of them lied. The issue is no one in their right mind is going to believe an ED.
Even from the crap the ED posted you can see the VM was way longer than 2 seconds.
