Hi, my husband and I just purchased our first brand new 2020 KIA Soul Saturday. We traded in our othet vehicle, got financed through KIA, signed the contract, and took our new car home. Now today they called and said they "accidentally" gave us a $1750 rebate and that it was a mistake since we financed for 84 months. They want us to come back and redo the contract and take away the rebate. Is this legal? After a deal is done and contract signed can they request the rebate back? This is not our mistake and I don't feel they should be able to do this.
