Suntrust won't work with my Attorney

I am on a forbearance agreement with my lender who is Suntrust. I have a law firm working on a loan modification but they are not doing to good for me. I have paid them money and that's why I got behind on the last 2 month since October I was only 1 and half months behind before I started with the law firm and I could not pay both Suntrust and the law firm at the same time, they said that they would be able to help me and now they are telling me that Suntrust wont budge to do a loan mod and I just got a call from the guy at Suntrust he left me a message saying that he is going to start the foreclosure as of tomorrow because I have not made a payment I want to start paying them with my next paycheck. I will allow them to take the money out of my account automatically but the past due amount is too much for me to handle its about $10,000. I will be going to court for my fiance he is out of work hurt and has no income at all but he is getting SSD. We go to court to settle the case that may take a month to go through though he is owed a couple years of money for waiting to get on the SSD. I will be able to afford the payments until that happens but I need them to be willing to work this out with me and I would love for them to put the past due amount in the back end of the mortgage with a partial claim and I will keep up with the payments. I know that there is help out there. My law firm told me that they would get back to me but I am not sure on what to do. I just want to get this worked out. Should I call Suntrust back or should I let the law firm call them back. I want to call them but I don't want to mess anything up that my law firm might be doing. I have 2 children and I lived in my house for 10 years I cant go through this I worked too hard for my home and losing it is not an option.
