Motorola Solutions — Delay in repairing display problem of moto g3 smartphone

Address:

Kolkata, West Bengal, 700048

I had submitted my smartphone on 04.01.16 at B2X Motorola Service Centre, Sree Bhumi, Kolkata due to display problem. They told it will take maximum 20 days to repair because o[censored]navailability of the display part. But till date it is not repaired even display part is also not received to them. Evert time I asked them when display part will come, similarly every time they wants 10 days simultaneously.
So how many days it will take to repair??? Kindly confirm me and please do the needful.
Thanks.
