Thank you for the response but I get this error message.
"Authentication failed - please try again or call 800-346-0508 for further assistance."
I also get that same error message when I attempt to pay using my phone.
When I was in the USA I called the telephone number as instructed but was stymied by the machine. The machine wouldn't accept the personal information that it asked for.
Now I am in a foreign country and when I tried to call that number, using the correct country code, I get the local "unable to complete call" message in Spanish.
That is why I've been scouring Verizon webpages for any way to contact support.
