Sony India — Mobile handset service - suspect

Address:

Erode, Tamil Nadu, 638002

I gave my sony (Xperia e4g) mobile handset to service at sony service center in erode on[protected]. At the time they told me that battery is the issue and told it will cost me 1250 and said handset will be ready to deliver within 1 week. After 1 week they said charger pin got damaged it will take another week and charged 100 extra. After another week they are saying mother board itself got damaged and charging 6000. If motherboard is damaged. I suspect they broke all my hanset parts and trying to replace and also charging me for that. If i refuse to pay the ask me to get my handset back by paying 150 service charge.
