Just touching base if you still need assistance?
It sounds like you have some kind of billing dispute? Not paying a bill is likely triggering that automated contact.
Not great to hear you're having trouble getting in contact, there are several options including calling, leaving a message, chatting, via Social Media etc.
That's odd about not being able to leave a message, are you able to try a different browser, clear your cache and temporary internet files, use a private/incognito browser, etc. or contact the Social Media team?
