GM Finanacial put a 30 day late on my credit report for XXXX of XXXX The company I work for pays the payment and they have stated that the payment was made at the same time every month as normal however the mail delviered it late or GM Financial processed late. 

In addition, GM Financial did not have the correct phone number on my account and I had called in two separate times to make this update and they did not update even after they had already reported this late payment I had an XXXX  score prior to this. I have never made a late payment in my life. 

Please take a look at this and help me. GM Financial is so difficult to deal with.
