Lenovo — Worst smartphone service

Address:

Mysore, Karnataka, 570027

I went to a service centre to resolve the issue with my phone and to replace my charger. They gave back my charger saying warranty has been voided. But the phone got even more touchless than before. And even after a month they could not replace the charger. And finally they did, but they didn't give the cable with it. I have never seen such a useless service centre.
