Terrible Samsung TV experience

So disappointed in my experience with Samsung. I bought my first Samsung tv a month ago, spending more than I budgeted believing that Samsung is an excellent brand. 3 days after the purchase I complained about a feature on the tv and was told the only way to fix it is to buy the top of the range tv (which I then researched on my own and it wasn't true). I wanted to return the tv to the Samsung store but was told they will only give me credit, which would be useless to me in order to buy a different tv, this was already the most I could spend on a tv. So I was forced to keep a tv I wasn't happy with and in my opinion did not deliver as promised. Another 3 weeks later I started noticing very bad clouding on the tv in dark scenes. Reported it to the technician and they came to my house and replaced the screen. This did not fix the problem and I reported it again the next week. The technician once again came to my house and I informed them that I'm not happy with the tv and I want this tv to be returned and refunded. It's my right as a consumer to return a product for a refund if I'm not happy with the quality and I send numerous pictures showing and proving the issues. The technician said he reported it to Samsung and they will be in contact with me. After 2 weeks of not hearing anything I contacted Samsung again and they referred me back to the service centre. I contacted the service centre and they say they are waiting to hear from Samsung. I gave it another 2 weeks and still no feedback. Once again today I contacted the person from the service centre and he just told me I should contact Samsung. And that's why I'm on Hello Peter now. From day 1 with the ill-informed sales people at the Samsung store, my experience with Samsung has been terrible, and that after I was so excited to finally have a Samsung tv. Never again will I buy a Samsung tv, even if I have the money for their flagship tv. I want this tv to be refunded so that I can buy something I'm happy with and worth the money I pay. But going by my experience so far I'm expecting this circle of communication to continue. Please Samsung, come and collect your tv. It even still has the plastic wrapped on the edges. Give me my refund and sell it to someone who doesn't mind the problems. I bought it on a sale so you can even sell it at a profit. Just please come and take it so that I can end this experience.
