Dell India — Inefficient service/staff!

Address:

560071

The same thing happened again and again:
We gave the laptop, inspiron 14 (3420) in the end of service warranty period with the problem "getting shutdown (Some times cannot turn on without any reason after normal usage" at the end of warranty period (I think after the period was finished) they returned me back my system and they told they changed the almost every part of laptop which includes mother board too. After i got the system back, the frequency of shutdown has monotonically increasing since it got repaired (At that time it was shut downing very hardly but now it increased drastically).

Few days back after normal usage and shutdown, we tried to on the system, but unable to on it. No response from any other device and led.

My concern is, how inefficient the servicing or servicing staff is? This is my second laptop (Previous one is dell studio 15) got repaired in the same way (Cannot turn on after the normal usage) and that both got the same problem after 3~5 months after the warranty finished. I also serviced my both laptops at the end my service period. How come these service technicians are inefficient in the prestige company? Or this is by intentional for non-warranty laptops?
