Complaint Review: Merrill and Associates law firm

In April 2015, my parent were contacted by John Davis for a loan modifcation. He sweet talked them to apply through his firm and guaranteed modification in 60-90 days charging them $2900. My parents applied and was contacted by one Sabrina Costello (senior processor). After sending over all the requested information, several other people kept reaching out to my parents for the same information which Sabrina had stated that its been sent to the Bank. We were further contacted by Mary Lopez, Alejandro Moldonado, Ninia Alliones. Each time they contact us, they ask for the same paperwork. None of them can give us any update to our case. After couple of months when the money had been withrwan from the account, they all dissappeared. None of their phone numbers work - 646-661-3045; 718-395-3158; 646-513-2645; 646-513-4481. This company is ripping people off from all over the place. We are yet to hear something from the lender or this company. As off now they are non responding to any call or email.  My parents need justice..
