Carmax Carmax the way car buying should not be! Carmax Gastonia NC NC

Ok first I must say that at one time I was a happy Carmax customer.... That being said Not anymore!!  It all started about 5 weeks ago after being hit by a drunk driver. My 6 month old new to me  Hyundia Genesis was a total lost..., the first car I've ever had that I truly loved! So after listening to my friendly Carmax salesman Don I was talked into buying a Gap policy....Thank God I did! So far all is well right??? Well after going to buy a replacement twin car I found at Carmax I was told I would need to take a higher interest rate or Wait for my car to pay off... As I have two car payments with carmax finance already..plus a $24,000 car with only 6 months of payments they were asking for a car to be traded. So this is where I turn from happy carmax customer to crazy mad customer!!!! The insurance of the drunk driver (Alstate) agreed to pay all but $2500.00  (thanks gap!) But the check from Alstate was sent to Carmax Finanice and for some strange reason returned to Alstate. Then a second check was mailed and cleared through Carmax Finanice.  Great now my debt was down all but what gap owed.... So off to Carmax to get my car.... Wrong the 2nd check that cleared was then applied back to my account?!!! What??? Then gap still had not paid.... So today I was told gap check was mail to wrong state???? I have money being sent to pay off a debt and they keep sending checks to wrong places..... It is bad enough to know that I was hit by a drunk driver but now being punished by people who can't do their job correctly!!!! I am still car less and Carmax makes it sound as though I have no right to be upset!! Plus when the put the pay off check back on my account from Alstate they added interest! What's Up Carmax...Cant even call you a (buy here pay here used car lot) if you won't take a check!!!!!
