I am in AR.I shipped brand new 6 disc cd changers to santa monica a car dealership.Well I received the check saturday.I went to cash the check and they had put a stop payment on it. I called them and they told me that they had opened 10 of them and 4 had worked So I said to ship them all back. Then husband called and he said that 10 out of10 did not work. They received them 2 Weeks ago and only reason I even spoke to him was I couldnt cash the check he had called to tell me they did not work or anything I believe it is some kind of scam. What should I do
