Ford ripping clients off

My vehicle has been at Ford from the 31st of December 2018 for repairs ,they took their time to fix it, and alway when we went there they would tell us it was something different. They called us to come get the vehicle on the 29 of January and on the way home we experienced the same problem we had when we initially took it in. We took it back to them on the 30th and they advise that the turbo is ****ed up and needs to be replaced. They don't want to assist with the repairs and they want us to pay an additional amount on top of the 26 500 that we paid. My question is what was fixed and why is the vehicle worse off than what it was. You call their offices, no one answer and when they do they promise to call back. The staff is rude and has no consideration for clients. I believe ford is ripping me off and i am not going to take this lying down. I am going to take further steps as I am not going to pay anymore money for God knows what. I have no faith in Ford anymore, I am broken, broke and so distraught at the service.
