Audio and video installation service near Somerset, NJ

I had a Horrible experience in this place. Every time I was trying to leave my car there for an oil change, I was attended by employees draging theyre feet and with a bad attitude. always telling me that it will take me from 2 to 3 hs to change my oil. Finaly I took it there and I left it. 2 hs latter they called me and tell me that my car have some problems starting... "Nothing is wrong with my car", I toll them, so I went to pick it up and they sayd they had to jump start it. I ask why and this guy starting acting defensivley and just told me my batery was dead (My brand new batery) So I ask if they did something to it and this guy got upset......... I sayd "if somebody should be upset is me!" My car was runing perfectley when I left... Oviousley what happened is that they left the keys in the ignition and crank the heat up , (I always leave it at 60 but I find it at 75) I mention this to this guy and he kept saing he didnt do nothing...Charged me and didnt eaven apologize or sayed good bye... Cherry on top of the kake! They drop oil on top of the engine and now the car smels like burnt oil when I drive, They also forgot to put the sticker with my next oil change milage on my wind shield! This was the first and last time I bring my car to this pathetic place!
