Greentree keeps adding fees that I need to pay, what can I do

I received a NOD on Friday the 9th of May, mailed on the 8th. I can catch up the loan by June 8th and the late prop taxes also but now I'm also being charged 1500+ for foreclosure fees and 1352 for advances on the loan? (I think this is from last Feb when I worked out having 2 payments moved to the back end of the loan). I just need someone to get them to add these two things into the loan and I would be fine. P.S. They also have the figures on the NOD padded. They say I'm in default Feb, March and April but Feb was paid back in March. I sent them $900.00 on May 9th before I got home and found the NOD in the mail and I know they did not have that yet when they mailed the NOD out, so right now I am behind $552.00 out of the $708.00 due for April and $708.00 for May that was due yesterday, May 11th. Also my back prop taxes from 2007 due are $1085.32, I just called and checked. On the NOD they have them listed as $1576.41. P.S. Just wondering on the missed Feb payment they list on the NOD. Could they have put that in on purpose even though they know it was already received so they could add in the (advances on the loan) amount? Just wondering if that is something that they could only add to the NOD before 12 months have gone by so they are trying to slip it in by saying Feb payment was not received before they made the NOD which is not true.
