Here is what you definately have got to do. Request a court hearing with the US Bankruptcy Court in the city & state to which has juridiction. Have copies of all your paperwork. Also conattc the trustee's office for teh chapter 13 payments as well. No one, including the IRS or any creditor included in the 13 plan, can violate the federal law. At the same tiem find the mailing address for the IRS and the creditors and mail them a letter of dispute. Make sure thta you get a tarcking number so you can track it on line. Priority us mail with delivery confirmation would be a way to go.
