I've been annoyed with them for so long and been ignoring them. I decided to finally answer and no one is there! I've answered at least 3 times to silence. What am I supposed to do if they're not even talking any more?
Add each number to your contacts. Then send all the calls from that contact to voicemail. Since they don't leave voicemails it won't fill up your mailbox. I see where they call but don't know they call until I go to my call log to call someone else.
This is exactly what happened to us. We were paying the hospital, they changed their name and now all of our bills that had been lumped together have been broken down into individual bills. They sent some of them to this company and some to another company. Now we're arguing with the hospital.
