Nokia India — delay in resolving the problem (display problem)

I have given my nokia 1 due to its display problem (Purchased from mantra mobile and which is within the warranty period) to your visakhapatnam branch (Name of service centre : bright infocom) job service no.[protected]/190717/002. But every time, i enquire about the status, they inform that the spare part is still not received.

Pls. Look into this issue and get the service done at the earliest.
