[Resolved]  Samsung — Faulty product delivered

I have ordered samsung galaxy s6 lite through the samsung website and on the delivery date it was working fine, but from the very next day, the screen started malfunctioning and black lines started appearing on the screen. Very next day the lines were increased and the entire screen was affected. I tried for a replacement, but the facility was not provided by samsung. I immediately rushed to the nearest samsung store and they are saying it's my fault, and i need to pay for the repair. How come black lines on the screen could be a mistake from the customer end. Even if we buy from e-commerce stores, there is a facility of replacement within/up to 7-10days, samsung neither provided that nor helping me by repairing it and asking for additional money for the same. This is completely unprofessional and unethical behavior from samsung. Request the concerned authorities to help me on the same.
