PATHETIC AND *********

I logged a return for my Samsung TV which does not have picture or sound. It still falls in warranty period so they came and collected the TV, bubble-wrapped with the remote, power cord and foot stands stuck to the front. Courier guy took picture. Fine. They don't let me know anything, I just see on the website it is declined. Call the call center - they say the screen was cracked when it reached the warehouse!! Will follow-up with couriers. Never get back to me. I've been phoning for 4 days. Then they send the TV back to me WITHOUT THE ACCESORIES and best of all THE SCREEN IS NOT CRACKED!!! Phoned them again - they will get back to me. Nothing. Phone again. Nothing. Meanwhile I've sent about 10 emails as well. Nothing! What do I do? They are supposed to refund me or replace the TV. They don't respond to emails or phone me back. They **** about the crack. This is *******!! Can someone please help me?
