Geraci Law Firm PFG Did not respond to erroneous claim, costing me additional $7300. No response to phone or emails. Chicago Illinois

I filed Chapter 13 with PFG Law Firm and thought I would be protected.  They allowed my ex to file a claim against my case for over $7000 which was to be paid at 100%.  The claim was not valid yet the trustee continued to make payments.  I have sent many emails that go unanswered, called after 2pm as stated to be told I'd hear back from them and didn't.  Now the ex has also gotten child support increased outside of this matter and I have very little money left after making my monthly trustee payment and paying other normal bills.  I spent my work bonus on bills to cover the extra child support and now risk having my case dismissed.  Still no response from PFG Law Firm on this.  I do not feel I've been represented and their fee has been paid in full.  I was told they would be there to provide support throughout the process until discharged in 5 years.  I haven't seen or heard from them since the hearing to approve my plan.
