Lenovo — Replacement of lenovo smartphone zuk 1 by new phone.( urgent basis)

Address:

Bhagalpur, Bihar, 812001

Dear sir,
I have bought lenovo zuk 1 smartphone in month of June 2016.After 15 days o[censored]sing it stopped working.I send the set to the service centre .There they returned me after 45 days.After getting back by service centre, within 5 months only, the touch screen touch function stopped .10 -15 times, the mobile automatically being switched off in a day, After receiving the calls and when disconnecting the call, mobile gets automatically switched off, its always heat up instantly.
So, I am not at all satisfied with this set. Sir please understand my problem if this set is not working properly since 8 months only from the date of buying the set. So I do not have any belief in this set and more critical situation is that service center is very far away that is 220 km from my working place.I am unable to take leave always from my axis bank as I Am employee of that organization.
Therefore, I need to replace this by new one.

Thank @ Regards
Nitish keshri
