Coolpad India — phone not repaired since last 1.5 month

I have submitted my coolpad phone (Coolpad mega white) job sheet no-js[protected] on 15/11/2017 at surat, gujarat.
I have talked 3 times with your employee but they are giving only one answer that still parts is not available so your phone is not repaired.
Now it's too long as above 1 month, kindly give me idea that what kind of service you can provide to me and also that by when my phone repires and handover to me.
I have not get reply from your side.
Kinldy update as service centre not giving proper answer.
Otherwise i have to move ahead and complain to concern team.
