Discovery health

I am handling my mother's accounts as she is 93 years old and cannot do it by computer as it is expected today. She needs to confirm her GP that she will use this year . However, it is impossible to find anybody to yet answer a phone. It is also impossible to get past the username and password on the website, even though I have reset the password and got notification that it was accepted. IV GET NO JOY ABOUT TRYING TO CONTACT DISCOVERY - IT IS EXTREMELY USER UNFRIENDLY !!!!!
