Who Called Us

It's an automated sysem that calls as a reminder of a private voice mail message from a doctors office. The system is called Mmail.

Is an automated system and obviously they're calling the wrong number and I can not get them to stop calling and leaving the long winded voicemail messages. I tried calling the number back and it requires a code but obviously I do not have. And then you go into a black hole without being able to and at the information to never get them to stop calling me. They called my number at least 10 times a day
