Unsatisfactory Service from Ford Credit

I am not happy with the back and forth I have had to endure with Ford Credit as of the 28th of June. I no longer own a Ford vehicle, and the balance was settled by the dealer that I have bought a new vehicle from. Ford Finance debited an instalment from my account, and I then shortly informed them of the balance being settled. They have since been going back and forth with me and are not refunding what is due to me. Today is 1 excuse and the other day it's another. I did all that was requested of me in terms of calling in to confirm if settlement has cleared from Ford's side. I again called in to do a finalization for the refund,and that was on the 1st of July 2019, but still I have not received what is due to me.

I asked to be transferred to Gloria, whom I spoke with on the 1st of July, but the phone rings non-stop.

REFERENCE NO: ***1

Not sure what more to do.
