Hi esox1112, thanks for posting and welcome back to our community.
Sorry to hear that your mother is having issues with a few call features and for any inconvenience this may be causing her. I'm also sorry to hear that she's having a poor customer experience when attempting to resolve the issues. I would like to look on yours and your mother's behalf. I am going to send you a private message. Please look out for the purple envelope in the top right of your screen.
Regards
Lee_R
