Asus India — Asus zenfone 2 ze550ml/ i am complaining about the non functioning of the google play store.

Sir,
I regret to state that, i bought asus zenfone 2 ze550ml from flipkart. The product was delivered to me on 16.06.2015. Thereafter, around the month of january, 2017 i noticed that the google play store is not responding. Thus i rushed to the authorized service centre of asus at chandni. The problem was resolved.
The same problem cropped up again after few day. I was so disappointed that i did not revisit the service centre and managed with that condition.
But most of the apps need to be updated from google pay store. Hence, i am confronting lost of problems, please help me out.
Many people warned me not to purchase asus product, yet i believed in it and bought the same.
Now, i want proper redressal of my problem.
