If it smells fishy it probably is. Collection companies have particularly questionable practices which is why they are so highly regulated. We suggest that you review all of the original agreement documents to see if a breach of agreement or breach of contract claim exists against them for the litigation post agreement. If you do not have a clean breach of contract in writing then you may have a fraudulent inducement claim amongst other claims.
