samsung bad service

I had the most terrible service with my Samsung Products. After a year I had to sent my Tablet in for repairs and it got 'lost'. Eventually they found it and they told me I need to buy a new battery and the motherboard was faulty. Then after 6 months I had my Samsung Star, it also gave broblems. They sent it in for repairs and after nearly a month I got it back on Feb 26 and it was still not working. So on Feb 27 I took it back again and I still have not received it. It is now the 20th of March. I am so dissapointed in Samsung and their products that I will never buy it again. I have sent Samsung emails and they hardly came back to me, I really think it is pathetic.
