I bought a car from them. After a week of buying the car it has been having problems overheating. I called the company and took it to their shop, which wasn't at the location I bought it from. After 3 days of waiting to hear back and they called the company that they have the warranty through and they say that I don't have a warranty with the car that it was a buy as is, which it wasn't and I clearly have a copy and proof of the warranty. So I call the Hubler that I bought it from and try asking them about why I wouldn't have a warranty and also asked them if I could have a copy of the vehicle observation because that's what the mechanic said I need to ask for. I waited on the phone for about 5 minute trying to get all the things I need then the person I'm on the phone with starts to say that everything was repaired when they had it (which clearly isn't true if it's overheating after 3 days of having it) and says that they probably don't have the paperwork I need and hangs up on me. I just want a car that I'm able to drive and not what they gave me... please help
