Another update: Acura does not handle transactions themselves, so there is no way a dealer won't know you made a reservation - the dealer is the one who charges you. The payment for my reservation was charged by "AUTO NATION STEVENS CREEK" so I called their sales team again to try and confirm that they had my reservation. As soon as I asked to confirm my reservation the sales person (gave his name as Ali) gave me a bunch of attitude, refused to even attempt to check or verify anything, and even told me that it was impossible and they had no details. To which I responded: "fine I'd like to cancel my reservation, then". He gave me the same bullshit about it being impossible and that he had no information on reservations etc. and told me to contact Acura. I contacted Acura customer support and they verified my original assumption (the dealer is the one who charges you) and told me to either ask for a manger at auto nation, or contact my credit card comapny.
Fuck auto nation. I've initiated a chargeback, they can deal with my credit card company.
I've made a new reservation with Hopkins Acura in Redwood City. This morning I called and spoke to Gilbert on the sales team, but it was pretty early and no managers were in yet and asked if he could text me later on. Just now he texted me back saying they've reviewed my integra order and verified the reservation payment went through.
I realize that making a new reservation this late might mean that I will have to wait longer, possibly months, to get my car. I don't really care - at least I'll be dealing with a cool dealer.
