Business ProfileforBMW of Waterbury

Purchased a vehicle on 8/30/2023, as of today (10/10/2023) I have still not received plates or registration paperwork and temporary tags have long since expired. This has occurred despite me reaching out to the business multiple times (9/22/2023, 9/29/2023) inquiring about the status of my plates/registration. Most recently, on 10/03/2023 I was told the plates/registration were being overnighted to me, but they have still yet to arrive, with no tracking number provided despite request. In addition to this, the business contacted me a month after purchase informing me that their monthly payment calculator was broken at time of contract and my monthly payment would need to be nearly 100$ higher (729.79 => 819.37) since it didn't include taxes. This is not representative in any of the paperwork I signed, and was not presented during negotiations. Despite multiple attempts at reaching out (beginning on 9/27/2023 when I was told the monthly payment would be increased), the business has failed to provide an itemized breakdown of the purchase, and how it resulted in this new price, or attempted to reach a resolution with me. Very frustrating and unprofessional.
