Westway Ford Deceptive Service Practice Irving Texas

Came to dealership on 10/29 to get my 2013 Ford F150 serviced. My initial issue was that my key would not come out of the ignition. At that time I did advised them that I have a Ford ESP warranty. They told me that they would have to do an inspection on the vehicle to determine the problem. After the diagnostic the service tech informed me that I had a broken shifter and a radiator leak. I told him to fix everything that is covered under the warranty. He called and told me that they car would be done 11/2 and that they wanted to know if I wanted the leak fix? I asked was it covered under the warranty, he (Johnny) said no, then I said don’t fix it. I just pay my deductible ($200.00) and get the leak fixed at a later time. He then tells me that they charged me for another diagnostic on the leak!!! I told him I didn’t authorize that and asked to speak with his manager. He transferred me to Harvish and he told me that they charge diagnostics on each issue on a vehicle and that I authorized it. I told him I did not!. I get up to the dealership to pick up my vehicle and Harvish refused to come and speak with me to discuss the matter at hand. They also told me that they would not release my vehicle until I paid the full price ($329.00). So I made 2 payment transactions, one for $200.00 and another for $129.00 in order for them to release the vehicle back to me.
