Samsung — Asking service charge for samsung mobile with manufacturing defect

Address:

Kolkata, West Bengal

24.08.2012; Purchased mobile Samsung. Model no. S5830i 30.08.2012: Traveled to Egypt 12.09.2012: mobile frequently hang. Samsung service centre, Cairo denied to change motherboard without payment. 10.04.2013: Samsung service centre, Kolkata changed motherboard with payment because it opened outside. 04.11.2013: Purchased charger from Samsung service centre, Kolkata because of charging problem. 05.05.2014: Purchased again new charger from same service centre for charging problem 07.05.2014: Purchased battery from same place for charging problem. 26.06.2014: Changed touchpad with payment from same service centre. 20.08.2014: Charging problem. Same Samsung service centre told either change motherboard again or throw it out and purchase new mobile. Because there is suspect of Manufacturing defect in the mobile and new motherboard may be not support again. April, 2015 I tried to make service outside of Samsung service centre, they also require to change motherboard. I logged complaint in Samsung customer care on 23.06.2015 and attended to the service centre on 30.06.2015 according to their instruction but they are asking Rs. 5047 for changing motherboard again. Sir, Why not detected the manufacturing defect in the early stage? They misguided me without searching the exact problem and wasted my lot money. Who is responsible for this defective mobile? Kindly solve this problem and allow free service of this mobile or change the mobile by new one. Thanks Tapan Kumar Gorain Mobile no: 91-[protected]/91-[protected]/ 91-[protected]
