I don't even know where to begin to correctly express my absolute frustration with DCH and I don't think "unprofessional" is a strong enough word to describe this place!!!
I bought this car used from another dealership. I lost my key and had it towed to DCH being that it was only a few miles from where I was after making an appointment with them and giving them all of my info and asked that TWO keys be made . When it was towed into the lot, the towing person let them know my car was there and I also called to follow up to be sure and gave them all of my info AGAIN. I was told it would be ready later on in the afternoon and they would give me a call to pick up. I understand people get busy so after about an hour and a half passed the time I was told it would be ready, I called to check the status. After searching and searching, they couldn't find my info OR my car in the system as being there! I have PENNSYLVANIA plates and this is a NEW JERSEY lot, I mean, it shouldn't be hard to find it. The woman I spoke with tried her hardest to convince me that I must've had it towed to another dealership. She then transferred me tot he service department where I was put on hold for 10 minutes, for them to come back and tell me they can't find my info or my car again. After 3 more calls and me DEMANDING that they FIND MY CAR ASAP, I get a call saying my service appointment was under the ORIGINAL owner's name, my car was parked in the back of the lot because they didn't know what to do with it, and basically they were waiting for someone to come claim it. I gave all of my info AGAIN and was told that my car wouldn't be ready until the next day. The man I spoke with was unapologetic and extremely rude!!! I have already lost a full day at work, given the run around for hours, and I'm very frustrated. I had to get a rental for the next day. I was told they'd call me around noon and let me know status. AGAIN I NEVER RECEIVED the call. Around 130pm, I called and called and called, no answer. I have to have the rental back by a certain time or they will charge me another day. I show up at the dealership to pick up my car. I am standing at a service desk for 10 minutes before one of the girls decided to break away from the conversation her and other girls/mechanics were having to help me. I'm handed my paperwork and ALL OF THE ORIGINAL OWNERS INFO IS ON IT!!! Yes, some stranger's info is on this paperwork that they gave me and ONLY ONE KEY, I ORDERED TWO. This $250 key bill put me in a hole almost $1500 between the key, rental, and lost time at work for my husband and I both. I had 15 minutes to get return my rental or be charged. Your rep told me where to find my car and it wasn't there, I hit my alarm button until I found it because I'd rather wander around your lot aimlessly than speak with another one of your employees again! I rush to turn in rental while my husband drives my car behind me and my TIRE LIGHT IS ON. SERIOUSLY DCH? After all of that, the tire light was on (wasn't when I brought it in ) but you couldn't fill my tire?
Your customer service is lacking to say the absolute least! I was not offered air in my tire, a car wash, not an "I'm Sorry" NOTHING from this place for costing me 6 times what this key fiasco should've cost me. STAY AWAY! I've been debating on contacting the original owner as well, seeing as I have all of their info, letting her know about this as well as a copy of the paperwork with her info on it. Had I been someone else, I could've done terrible things with this person's information. I SHOULD BE SENDING DCH A BILL AND DCH SHOULD BE ASHAMED OF THEMSELVES.
Your "multi-point inspection policy" is BS too! You missed my low air light!
