Worst communication experience ever

After some initial hiccups with my application due to a sales person leaving and seemingly without any handover, we finally got approval for a vehicle. We weren't told the waiting time, but anticipated some delays. Following many follow ups with little or mediocre responses and a sales manager who in my opinion has no understanding of how to interact/ communicate efficiently with customers we decide to ask the dealership to also put us on a waiting list for another vehicle and asked if we could do so without additional applications. No response after 2 days. We decided to cancel on this principle, "if the dealership cannot value customers (even those deemed annoying) enough to communicate, then how will the after sales service be?"

I decided to follow up about being on a list for a different vehicle and was told "we saw your emails but didn't respond because we don't want to say the same thing over and over..."

The sales manager needs training, it's ok right now since the cars are "selling themselves" but what happens when that comes to an end?

Ihad a great deal from them, but maybe that's why they treated me like they were doing me a favor??
