I took car in for oil change & service. Oil change NOT completed, (I guess because it is a free service), & now there is fluid or oil drops coming out the bottom of the car. The next day, I checked the oil myself. The only oil in the engine was black & thick, like tar. Clearly, NO OIL CHANGE WAS PERFORMED!!! I now have to commute & go back a 2nd time. I called & spoke to Mark, service manager. During our conversation on phone, he tried stating that it was my fault because I hadn't been there in awhile, (I WONDER WHY)?!?!?! He accepted NO RESPONSIBILITY for any wrong doing. When I take car back, I will only allow them to complete the oil change & find the reason for the leak from the bottom. I will be watching EVERY move they make & I WILL NEVER RETURN TO THAT MESS, EVER AGAIN!!!
