Transmission King Chuck Kinard Jr. Told me my transmission problem and cost and called next day with a triple cost amount Loganville, Georgia

I called transmission king in loganville,ga. and told them my van transmission was slipping in 3rd gear and I was told by the owner Chuck to bring the van there and they would check it out for free and call me with the problem and price to fix it. This was on 12/21/09. We drove the van to transmission king and left it on 12/21/09.  
I was notified by phone from the meachanic and was told the transmission clutches were bad and it would be $489.00 plus the price of the new clutches which would be a tatal of around $700.00.  I told them thank you and to go ahead and fix it.
Today (12/22/09) I got a call from the mechanic and he told me that he had bad news for me and that my transmission was totally shot and it would be $1.500.00 to repair. I told them I couldn't afford it and was then told it would still be $489.00 for them to put the transmission back in un-repaired for me to pick up the van. We drove this van there with only third gear slipping but was told the van would not drive when we picked it up. They said I would have to have it towed.
I talked to the owner Chuck and told him that I would pay the $489.00 for them doing nothing but I wanted it to drive out just like it drove in and he cursed me over the phone using the "F" word and was very rude.  This company called me with a price and the next day almost tripled the price and now I have to pay $489.00 to get my van back that now has to be towed. This is very bad business especially here at Christmas. I guess someone there at transmission king needed Christmas money and didn't mind taking it from someone that now can't afford Christmas.
On 12/23/09, I called Chuck and told him it would be after Xmas before I could pick my van up and he said he couldn't wait that long. His meachanic Tony called me and asked if I was picking up my van and I told him I would just see them in court and he got nasty and stated that I would surly lose and lose my van too. He hung up and then called back saying the transmission was in the back of my van and I could pick it up for $400.00 cash that day instead of the $489.00 he wanted that morning. We drove this van there with only 3rd gear slipping and now they want me to pay them to have it towed away with the transmission laying in the back. These guys are really something. Transmission King also has other complaints against them so beware.
I hope no one will ever trust Chuck and transmission king. I was totally ripped off.
