Lenovo — lenovo k8 note service

Address:

Bangalore, Karnataka

I am very unhappy with lenovo service. My lenovo k8 note has poor reception, frequent call drops and loss of signal. I have submitted my phone twice and still not resolved. The service center said they changed antenna while the technical support team is saying they have only observed the phone and returned after one week and later that the technical team was ' kept in the dark'

Lenovo management is not responding to my issue and they are asking me to submit without assuring anything. Very unprofessional service.
