Asus — No proper customer support for Nexux 7 tab

We had purchased google nexus 7 2013 version on 27 th may 2014 from flipkart. We used just for 2 to 3 months Later on, it didn't start up at all. We took it to asus service center located at chinchwad pune on 09/09/2014. Since then there was no follow up from their end. It was we who would go to the service center to get updates. We were told that the mother board wasn't working so they had to replace that and they had placed an order for it. We again went after a week and at that time they said secondary mother board wasn't working too and camera too had to be replaced, so it ll take some more time. Then again when we called up after a week, they said they had sent it to Mumbai. Now last week when we enquired, we were told that the battery isn't working. We are totally disappointed by the service provided by asus. Its been close to 2 months and we haven't received our tab. Also, its always us who have to do the follow up, there's nothing from your end. We had purchased the tab for some important work which is suffering because of this lousy service. Totally unhappy with the service and don't wish to continue with this type of horrendous service.
