Is there an attorney, who could assist me in a possible action against my recent attorney used AND the Department of Revenue ?

DOR used incorrect figures to over-calculate child support....ATTY advised they would handle....they did not, so the proposed incorrect amount stuck and ATTY office played dumb...This HIGH payment resulted in me & my 4yr old being homeless....then the DOR took an EXTRA $1k from me due to clerical mishaps, said Id get a credit....ATTY office charged me $600 to respond to a motion after not getting docs from me for OPC (although docs WERE sent in already, they played dumb again) Then we get a new temp agreement to help ease all the above issues, agreed to soley upon the terms stated....DOR somehow sends my tax return to kids mom on 2/19, despite all balances ect, being cleared as of agreement signing on 2/6.....And then I find the $1k credit , has vanished into thin air from DOR
