A & B Mortgage Consultants

I recently went to A&B Consultants for help with intentions of them helping me Buy A home I was told there were some issues with my Credit Report,and I was asked to give this Company $350 towards service but I was only able to give $200 at the present time and it was excepted. I was told that with the $200 dollars she would be able to clear the items on my Credit Report that was affecting the purchase of me buying a home, and A&B consultants did not do anything that was promised of them. A&B Consultants has had my case since 10-27-2012 til current, and has not done anything everytime I try and contact the person working my case she would just send me to voicemail, and when she did finally answer my call she told me not to worry she will be refunding my $200 by personal check which I never received and when I try contacting her on 2/04/2013 her exact words to me were; Dont call her no damn more! I am a disabled person that she has taken advantage of and I would like for someone to help me with my situation.
