They called daily at least 20 times a day, i don't answer when I do not know the caller, they do not leave messages either. How can I stop those calls?

Two Words. David's Bridal. They solicit your phone # if you dont check a tiny box on their form that asks if you want to be in touch with other wedding vendors. I am very upset with how many calls I have received. You can call them and they will update your info to be taken off their vendor list, we'll see if that works.

It is annoying. They are constantly calling and when you pick up it is a fax number. If you let it go to voicemail, it fills up with beeping fax sounds

This is a criminal collection organization. Go to their website, IMMEDIATE CREDIT RECOVERY, click "Healthcare", and then click the link to their HIPAA privacy policy. Read it carefully. They have access to all your medical records if you owe for medical (in addition to every thing else), and are not making any guarantees as to the safety of your private medical information with their employees. This company should be reported to the Attorney General in every state. If they call you about any medical payment issue, make sure that you report them right away.

Calls frequently if call back just on hold

keeps bothering me.
