Lenovo ****ing sucks

I don't even want to give it 1 star. Worst service ever!!!!!!!!!!!! Lenovo (they) have been fixing my laptop for 4 months now. I bought a NEW laptop and I have not gotten a chance to work on it properly as there are so many problems with the thing. It makes me so fed up that they are refusing to give me a new one or give my money back as it's been in to get fixed for the 3rd time and no response whatsoever.I think they have the worst service. As they are trying to replace everything in my laptop with old models. At the end, I paid sooooooo much for a second hand. No ****ing thank you!!!!!!!!!!!!!!!!!! I want my money back. I am not struggling with this laptop one ****ing time more.
