I have purchased Sony Television from East Coast TVs. I paid around $7, 000 and the shipping included in the price. But I got phone call from the salesman, who told me that my ordered model didn’t have USB. I said that I needed USB and he sent me a link, where was the similar model with USB. The price increased and I changed the order. But after that I haven’t heard from this salesman. What do I need to do now then?
