Peugeot Dealer Delayed Delivery of My 2008 GT

I bought a brand new 2008 GT model car from Samsun Demir Peugeot dealership on September 27th, but they haven't given me the car yet. They say they still need to update the software. It's starting to become a big problem! Every time I call customer service, they say they'll give me the information in a week, but they never actually give me the vehicle. This situation is really frustrating and not okay. I want my car delivered right away. I'm really disappointed that even though I bought it, I still don't have the car. They keep giving me excuses for the delay. The dealership not keeping its promise is making me really frustrated. I can't wait to finally get my car, and I expect them to hold up their end of the deal on time. The ongoing delays with no clear solution are really frustrating and discouraging.
