Lenovo — mobile a6000

Emei/sl. No. 8078y[protected] had booting problem.
I approached authorised service centre on 21.8.2017 to
Multip0le power systems, sree gokulam towers, no 306, 100 feet road, 7th street corner, gandhipuram, coimbatore 641012. They rectified duly formatted. After 2 days i got the same problem. The service centre people said, it has some software problem which will cost 70% of the original cost.

Mean time i purhased one more mobile p2 model.
Now i afraid of this mobile also that what should i do if it get such irreparable problem. Within 2 years.
