I brought my Cadillac in for service, and instead got scammed. The price that was quoted, and agreed upon was raised by a significant amount, after they performed the service, without consulting me. After 30 minutes of trying to resolve the dispute, i gave up, and requested my keys. After another 45 minutes of begging my keys were finally returned. I was threatened with arrest, and the police were actually called. Allegedly I could have been charged with "theft of service" for paying only 90% of what they demanded, which was already more than the quote i agreed to. In the end i paid the full amount. Still it is disgusting instead of treating the situation with respect, I was treated like a criminal. Whether these people believed i was right, or wrong is irrelevant. There is no reason to treat a customer so horribly.
