Lenovo — Having trouble with Lenovo Zuk Z1

Address:	122002
Website:	Lenovo

Hi All,

i bought this Lenovo Zuk Z1 mobile phone from the flash sale in May 16.
After the use of only one month, this phone start creating so much trouble for me .
Firstly there was network issue.This phone was not able to pick up any network.
Service center people changed the motherboard, saying it won't cause you any problem.
But real problem started just after that.It started getting switched off in every 2-3 hours by itself. And then frequency increased by getting switched off soon after it starts.
I went to service center again because that was the only solution provided by lenovo helpline people.
I visited the service center on 25 Nov 2016. and they asked me to submit my phone.
that's what i did. According to their estimate, that should have taken only 3-4 days to repair my phone.
But after 20 days (today 16 Dec 2016 ) i didn't get my phone back.

I trusted Lenovo and this is how you shattered my trust.In last 6 months this phone has created so many troubles for me.
Now you people tell me, what i supposed to do, Should i take this matter to consumer court, or you guys will provide me some better solution.

I am attaching the Invoice and service center slip.

Waiting for a reply.

Regards,
A frustrated user.
