Takes Money quickly but I have to wait forever the get MY money back

I bought a tv from them to pay of on a monthly installment. They took the Money and inly after said that my husband was not approved and that the money will be refunded. It was been 3 weeks and still nothing. They had send a email on the 10th saying that the refund has been processed and will take 5 tot 7 working days and still no refund. I will never buy anything from them again as they take the money very quikly but then if they need to refund you they take forever to do it. Not very happy with the service I have been receiving
