Treated unfairly from Game store Pavilion

Hello, I'm Sibongile Khabanyana from Westville, my details are as follows, email is ********** and cell number is ********** 479. On the 5th of September 2017, I bought a dell laptop at Game store Pavilion. After months the laptop began to have problems with keyboard buttons and charging system. When I took it back to the store as it was still was still under guarantee, after three weeks to a month they called to tell me that the supplies refused to fix it because of liquid damage. What surprise me is, I'm sure my laptop had no liquid damage when I brought it to them, now I'm being held responsible for something I didn't do. The way the managers handle the whole matter is very unfair and its turned to be a laughing matter. Will anyone assist me on this matter. This has taken five months and no one seems to care at Game Pavilion. Thank you in advance.
