(450) 348-3537 calls my cell phone with faxes often. Have tried sending them a fax asking them to stop but it won't go through. Have also tried calling, but can't get through that way either. I finally did some research and found a phone number for the company - Adrot Fax-Marketing - (450) 348-7974 and was able to leave a voice mail asking them to stop trying to send faxes to my cell phone. Hopefully that will take care of the situation.
