BMW of Murrieta

I purchased a new BMW from them. First, they totally low-balled me on my trade, then the salesman promised us a really nice gift since we purchased a car from them. A month later and I am still waiting for this so called gift. When we purchased the car the finance manager specifically stated that if we brought in our pink slip he would credit us back the money that we had to pay to order one from the department of motor vehicles. We called the next day stating that we had gotten the pink slip and would be bringing it in that weekend. No phone call back, no messages, nothing. We turned in our pink slip and the guy we gave it to said they would immediately credit our account which they never did. I called back three weeks later, left another message and was finally called back, the finance guy stating that "it has already been processed, there is nothing I can do." I guess BMW of Murrieta needs $52 more than I do because he stated I wasn't getting the money back. What a piss poor way of doing business. Promises, promises, promises and no deliveries on any of them. I will be using another BMW dealer in the future and have told all my friends and family as well as a lot of my contacts on social media about my terrible experience and to avoid this dealership. I will be using another BMW dealer in the future and have recommended to everyone I know to use another dealer as well. This dealer DOES NOT APPRECIATE THEIR CUSTOMERS. Very disappointed in your dealership. You have lost me as a customer.
