Citibank Debt Collection Complaint

Citibank Debt collection department,

Other (i.e. phone, health club, etc.) Cont'd attempts collect debt not owed Debt is not mine Texas

I never did this program and never received money from a loan or supplies to take these classes. They filed a lien against me and never served me papers so they violated my rights by not allowing me notice to defend myself in a court of law. Also who received the money from this loan? This is the - - and it is a fraud program that is why I never enrolled. Please put a stop to these illegal actions of falsifying court records saying they served me. I would like proof of who signed those papers please. Thank you for your help this is very disturbing! And is showing up on my credit that is how I found out about it.
