Welcome to the board
Only way is going to be by getting a goodwill deletion and you wont know until your try.
I sent a goodwill letter by email on 07/10/2018 and just received reponse today 07/18/2018 that they will be removing the one late payment reported on my sister's account. I've been helping her tackle her credit repair and it finally has paid off. The first letter I sent in March and they didn't grant her request. Sent it the second time and now it's going to be deleted. Don't give up!
No giving up here! I've got to do it. I e-mailed and received a reply that my request will be reviewed and I will hear something within 3-5 days. Will post an update!
That was the same response I received on monday 07/16/2018. Then just a few minutes ago I received the email with the attached letter that they will delete the late payment.
