Stop a blocked caller leaving voice msgs

[Sally+Forth]

I have blocked a caller pretending to be my granny, asking me to call her back. I suspect it would be a premium line.  I have no granny and so have blocked her.  She has been callling me for years and, if genuine, I guess she would have got the message by now.

Although blocked, she can still leave voice msgs.  Is there any way to prevent her leaving them?

thanks

ps. I don't think I'm the only one to have this problem but I haven't been able to find a solution yet

I think issues like this have come up before on here as I don't think there is anyway to block someone leaving a voicemail messsge,

You'll need to explain clearer what you're trying to do...
