Talked to a lawyer, gave my banking info, and agreed to allow them to take a certain amount per month. They sent paperwork and I also filled it out, again giving my banking info. They never did take anything out. Got something from court in mail. So I typed a letter telling them I'd agreed to allow them to take it out of my account monthly and since they were not, now I'd be sending them a 10$ check each month. Sent 3 checks and this past month they garnished my wages. I called the lawyers after finding out from my payroll. I was told that one number was off on the checking account I gave them (I verbally told them & filled out a paper with it on there). I was told the garnishment could not be reversed. These people do NOT want to work with people. They lie and then just garnish your wages.
