Seagate — my seagate 2tb hard disk is is having problems again and again

I had brought a seagate 2 tb harddisk which is validity as it is with me not even from 1 yr and it is having different problems again and again. I had exchanged the harddisk more than 2 times because of its problems but still i am facing lots of problem. I want compensation i had wasted so much money in it and it is again not working. 2 times it had gone dead and now files' location is showing but files are not opening. All my data is lost each time. It did not even fell once but still these problems our occuring again and again. I am trying to open it from 2 days but as soon as it takes 99 percent loading it stops it doesn't go to 100 percent. I even left it to load for 3 hours but still it did not completed. I want not only replacement but a good replacement and also compensation for all the money i had wasted in its data recovery each time.
