XFINITY EMAIL SECURITY ISSUE

I recently tried to log into my Xfinity email and was bombarded with errors and password incorrect till Xfinity pushed me through to another users account THIS LOOKS TO BE A MINOR STRUCTURAL ARGUMENT ERROR WITHIN SOURCE CODE and should probably be addressed soon until this falls in the wrong person's hands trying to save Xfinity from a lawsuit but can't contact them. XFINITY if your seeing this PLEASE FIX
