Call your payday loan company and get the actual standing of your account. It is their duty to update your file with the bureaus. Send a letter to them explaining that the said account is not reflecting your actual credit history.
Regarding the collection agency that is contacting you, send a debt validation letter to them requesting for the complete details of your account. You need to know first if they are the actual holders of your account. Later on, you can send a letter to them saying that the account has been paid off and updated in your credit report. Thus, they are required to stop collections. This is their contact information.
