Nokia India — nokia 5 screen problem

Address:

Paschim Medinipur, West Bengal, 721301

I have purchased nokia 5 on 16/05/2018 but screen was faulty, in just 28 days o[censored]se full screen became white. Submitted my mobile to nokia service centre for repairs on 14/06/2018 at paschim midnapur centre (Jai jalaram enterprise) but still they have not repaired it. They want again 48 working hours for repair. (02.07.2018) means another week, after several call to customer care, it is still not solved.
Service centre has not provided us other handset to use during the service period. I am facing too much of problem due to this. I am suffering mental harrasment and financial loss due to it.
