Review Ordered TV online 29/11/19. Tried weeks to return. Still not refund 21/01/20

I ordered a TV online on 29/12/19. Tried weeks to return (call centre did not answer, no reply to email). Finally they collected 09/01/20 after numerous calls and weeks wasted on phone. As at 21/01/20, l still can't get refund as V&A Waterfront store where they sent TV to has 'not processed return number". Shocking service. Will never order form them again and am telling friends not to either. Brandon and Nicole at call centre are trying to help but they are getting nowhere. Order #********
