Samsung — From the day 1 of purchase the phone started giving problem

Address:

Kolkata, West Bengal

I have purchased Samsung mobile GT-S5282 on Feb 2014, from the day 1 it’s having problem. Its “display become white and unable to scroll down”. Taken to the customer care & they told they have replaced the mother board. Hardly two months passed it started showing same problem. Again taken to the customer care & they have done something and given back the phone. After 2-3 weeks its problem started again then I used to take off the battery and after fixing it started working. But at last in the month of Nov again I have taken to the customer care for the same issue and its started hanging. But they informed after formatting phone will be ok. But nothing happened so I have to give it again to your customer care on Jan. 2015. (Sl.#RZIDBO5Y05L, IMEI/RSN#[protected] So suggest me how to solve this problem. Now it is in warranty period so you are giving free service but after warranty period if same problem arises what to do?
