Budget Transmissions

I took my car into have my transmission diagnosed. First off they told me i can get a free tow and diagnosis. It gets towed there and an hour later i get a call from Nathan the owner saying that i either need a rebuild for $1100 or have a rebuilt transmission put in. So i get down there just to take my car somewhere else for a second opinion.......the owner then tells me i have to pay for the tow and the diagnostic.we started to argue over it supposec to be free. And he tells me "Now im going to make u pay much more than anybody now because youre giving me trouble". So basically i had to call a police officer to get my car outta there. In fact while i waited Nathan the owner has my key, gets in my car, and drives it into a dock and blocks it with another car!!!!!!! I eventually get my car outta there and take it to "My tranny shop" across the street and am told that there is absolutely nothing wrong with my transmission. So this place is a rip off and they try to screw people out of alot of money for work that doesnt need to be done.
