Bad bad bad service!

I purchased the samsung note 10+ LED cover through a samsung promotion last year. Upon receiving the cover, it has been noted that the cover is faulty and does not work. I did contact the Samsung head office (numerous times, over 50 emails sent, back and forth)... finally someone gets back to me requesting a formal report from a Samsung store (re: condition of cover), my ID and my bank statements... I was informed that I would receive the refund in 4-6 weeks. Months down the line... no refund, no feedback... sent 3 emails these passed few days... no response whatsoever. Samsung, this service SUCKS BIG TIME! I truly support the brand, samsung TVs, samsung phones, samsung refrigerator, samsung microwave etc. And this is how you treat customers? Pathetic! I want my money back NOW. I AM NOT WAITING 1 DAY OR 2 WEEKS OR 3 MONTHS. I want my money! I want my money! I want my money!
