Purchased a used 2014 Toyota Corolla back in February and I was helped by the salesman and so as the manager named PJ Mehta. Everything went smooth except when I was given the keys...apprarently I was told that the previous owner has not returned the spare keys yet and I should get them once I pick up my tags. Three weeks came and I have not heard from them about the tags so I decided to call myself and check. The tags actually came two weeks after and it was just sitting at their office without notifying me. I found this out because the dates that it was recieved was showing on their filing cabinet. I again met my saleman at the used car office and he help me install the tags. As soon as I ask for the spare keys he told me that the previous owner never returned it. This is when I asked again PJ and he told me that they unfortunately do not have control on this and that I will just either pay for one if I really want them. At this point I was unhappy cause everything got switch...so he said that he can work on something out in terms of the cost since I also complained about the tags that was just sitting with no notification. I felt that they just want the money upfront and care less after they got you sold. Then pj offered me a discounted cost on the spare key and said he will work on the cost once he placed the order for the service center. The part came in and when I decided to schedule an appointment after 5 months I was told that there was no notes on the adjustment cost and I will have to pay atleast $300 just for the programming. Front desk person said that PJ was at the meeting until 10am to verify something since I said that they should have notes about discounted cost...so I waited and when I finally showed up around 10:20am with no follow-up call; guy said that there no notes at all. I tried to call Pj's desk but someone answered instead and told me that pj wont come in until 1pm. I went again and told the front desk person that someone said that he wont be in until 1pm...so who did you confirm this to? He replied and I dont really know. This whole thing became a disaster so I said forget about it. I even emailed Pj Mehta about the current situation but never heard from him at all. I wish that from the begging the sense of urgency is being in placed and the customer service is being executed all thruout the sales. Unfortunately it stopped right away once you sign the papers. I hope this wont happen to any of the people who is trying to buy a new/used car at this pace.

I had a call right away to escalate the issue and was so thankful that this will be resolve soon.
