I purchased Sony WX80 camera on 19 Feb, 2015. It is under 2 years warranty.
just after few months use, its zoom button stopped working properly, it gets stuck in between while zooming in and out.

There is a black spot in LCD pannel while zooming. HDMI socket is not working. its not getting closed.

We gave the camera to Chaitanya Electronics(Sony Authorized service center ) in Chinchwad pune on 7 Nov, 2015. But till now there is no response from them. We called many times, but everytime the response from them is different. Sometimes they say it will take 1 more month, sometimes, they HDMI socket will be repaired but rest things not.

Till now, no proper response from them;

Pathetic service Chaitanya Electronics is providing.
They don't believe in customer service, they just believe in befool the customer.
