Hoshiarpur, Punjab, 144205

Hello dear,
I purchased a laptop of your company from digital world jalandhar on 20th jan 2018 this year. It is wearing serial no. 4gqkyl2. Now a hardware trouble has been seen on screen. A horizontal odd line is appeared on screen. Photos of problem and tax invoice are attached herewith. My device is under one year warranty. Pls do help me to get your best service. Before this i lodged a compliant about slow working of device. Your service could not solve my problem then.
