AutoNation Toyota South Austin

I bought my vehicle in the beginning of November 2020 and a week later decided to cancel the add ons I had purchased. I was told this wouldn't be a problem and I would be credited the amount back to my total amount financed. After almost 5 months of back and forth, I still have not seen the money come back and which I am still earning interest on. I keep getting answers that say it should be any day now but this has been going on for months. My last email asking for an update has gone unanswered. I will say that the sales customer service was good and the initial interaction with the finance department was good, but this experience with the financial piece has left a sour taste in my mouth. This was my first time buying a brand new car and it will likely be my last time after this experience.
