Worst service -delay more than 52 days

I had problem with my XOLO q800 mobile, so I have submitted my mobile on 28/05/2014 at Deprosys service center-Chennai. When I contact the service center they said that the mobile is not coming from company. When I contact the XOLO customer care they say the mobile is under repair. Days passed more than 52 days till now they are not giving the final date for delivery of my mobile,
Model Name: XOLO 800
Work order no : 310000467021
IMEI No.-911306750361627
Take necessary action,
