You do not have to pay anyone to write a QWR to your servicer; you can do this yourself. You can use this sample QWR letter to make the request yourself.  

Remember to:

• Make sure that your QWR is sent to the address that the servicer uses for receiving QWRs
• Send the QWR separate from your mortgage payment
• Send the QWR certified mail, return receipt requested so you will have confirmation that your QWR arrived
• Continue to make your scheduled mortgage payments
