I purchased Lenovo zuk z1 mobile from amazon on 21.9.16. Said mobile is under warranty. Its Sim tray got broken.i approached company authorised service senter at sector 10noida UP on 2.12.2016.after 3 days they returned my mobile stating that sim tray is not available and whenever received will ring me up. Till date it has not been provided to me inspite of many visits to their above said service center. So I wrote to executive director service of the company and head service. But they just kept quiete and do not respond to my mails. Hence I m not able to use my mobile. This kind of deficient service is rendered by lenovo..which is nightmare for me. As I have been waiting for so long I have bought another mobile but not of lenovo.
Kindly take up this matter with the lenovo mobiles so that I can use my mobile if they can provide a sim tray for my zuk z 1 phone which is in warranty.
