You are not on "lending trees call list". You submitted an initial application with all of your personal/contact information in it. Once you submitted everything, lending tree automatically sends your information to all the different lenders or financial institutions that can possibly accomplish what you were looking for. In order to have your information removed from the system and stop the incoming calls/offers/emails, you will have to reach out directly to lending, and delete your account.
Yah that needs to be a huge disclaimer on their website. I'm really not happy with the service provided. Use rate finder instead. They give you the information for free and only have the person you select call you.
Anyways, just tried this. Hopefully it works, only have to deal with the insane amount of calls for another 72 hours :-(
