Reporting faulty product to their service center

My girlfriends G500 Lenovo purchased in 2014 does not go past the start screen before entering the operating system. <br> <br> I tried to help out by looking at the online help guide. After an hour I found a number that I could call. After being referred to a number of people, I was given a number that does not work ***. I googled the number and it seems the correct number is ***3 but there is not answer on that number. <br> <br> I again googled and found a page that says partserve does Lenovo's repair work. There a number is listed but I have not phoned it yet seeing as my faith in Lenovo has been last at this stage.
