Nationstar Mortgage Dragging out my Loan Modification Fort Lauderdale Florida

After three times insisting I qualify for a Loan Mod they approved it. I paid my three trial period payments. Their website shows I haven't made a payment in four months. I am getting collection calls daily because they a showing I am underpaying my original mortgage (hence the Mort Mod... to pay a lower amount). I have emailed my dedicated loan specialist Liliana.Sanchez@nationstarmail.com she never responds. I get emails indicating there is a new msg on the mynationstar.com website, but like I write above, the website isn't updated. So i call and am told I need to sign the Final Mort Me d documents that havent been sent to me yet (it's been a month since my third and final "trial period" payment. I made it perfectly clear to Ms Sanchez and every C/S Rep I talk to that I will NOT pay a fourth "Trial Period" payment... I won't be paying anymore payments until I get the final docs and have enough time to go throug them with a fine tooth comb these people are scums and cheats. I don't trust them at all. 

Congress needs to de to pass a law prohibiting original loan companies from selling your loan to a subpar company without your permission. I chose BOA for my original loan. I HATE Nationstar.
