Lenovo — Defective charger not replaced since 20 days

Address:

New Delhi, Delhi, 110092

I bought lenovo z1zuk last month, it wasnot been a week and my charger was dead, i visited the customer care in laxmi nagar delhi. They said it will take a week to replace the charger so i gave them my charger to get it replace now its been around 20days but i have not received my charger yet. No one is concern about the problem i been though without phone as i dont have a spare phone that support nano sim.
Worst customer care service ever experienced. Definitely not gonna buy lenovo again.
