Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
To clarify, are you wanting to use voicemail service from the phone company, or to use the answering machine built into the panasonic?
I can help you by phone, if you prefer.
Otherwise you may cancel from the help page.
I'm sorry I'm not quite clear, do you want to cancel entirely? Or just want to have an answer here via chat/email instead of an added call cost?I can send a note to customer service to cancel the whole thing, if that is what you wanted.
Do you need more help with this?
