Lockhart, Morris & Montgomery Inc. Debt Collection Complaint

Lockhart, Morris & Montgomery Inc. Debt collection department,

Cont'd attempts collect debt not owed Debt is not mine Texas

This company continues to report on my credit report after I sent them a letter telling them that this account was not mine and I have no idea what it is or who it belongs to! I asked for proof of a signed contract, I asked for a license to collect in my state, I asked for copies of all information referenced for this debt and still to date, I have not received anything but harassment from this company! THIS IS NOT MY DEBT!
