Already disgusting Service and I haven't even closed the deal yet

I have never dealt with a Company this size who has absolutely no customer service.. The sales guy Sameeg Sasman doesn't phone back, he doesn't follow up and doesn't reply back to emails or messages. Vanessa the finance lady that is submitting my deal to the bank also doesn't phone back when she says she is going to and I get absolutely no answers out of them why they are taking so long to get the deal done.. I phoned my bank to find out what the delay is and they say its Getworth that's delaying. When I phone Vanessa she says it's the bank.. So I am baffled. I have never been treated like this. Normally car dealers do their best to get a sale done and get it approved, but not this company.. I'm actually terrified if the deal has to go through, what type of afterservice I will receive if there is an issue with the vehicle.
