INFINITI dealerships near me (Brownsville, TX)

I had a horrible experience with Bert Ogden INFINITI in Edinburg, Texas. I spoke with Santiago the Sales Person and I told him I would be going at 7pm on a Wednesday. When I arrived, I was waiting in the Lobby for 25 minutes. I sent him a second message and told him I was leaving. No one offered to assist me. The next day Santiago messages me and tells me the vehicle sold the day before on Tuesday! I was very upset and called the General Manager who then tells me to keep looking and if I find a car I like, I can call him directly. I thought to myself, if I was a manager, I would have told the customer I'd look for them and call them if I run across a similar call. After my major inconvenience the last thing I wanted to do is call them again.
