Faulty laptop

On 02/04/2014 we purchased a Packard bell laptop from Game Kolonade. In October 2014 the screen started to show up but only half of the picture was visible. we took the laptop to Game Brits ( Where we stay) and sent it in for repairs. We received it back on 29/04/2014 and we were told that a software update was done. All our info, pictures etc was lost. On the 6th March 2015 we had to return the laptop because the screen was totally blank when the machine was started. Again we were told the machine has to have a Software update( Via a phone call).....?? In our home there are two other laptops that are running perfect (One is an Acer) and in our ownership for much longer which has never been in for repairs or a \software update"). I don't believe that this is a software problem but I do believe it is a faulty machine....am I going to have to send this laptop in for a \""software update\"" every 5 to 6 months?"""
