Nokia — Iron bridge alappuzha kerala bad service

Ihave paid Rs4000/- as advance for the display of my nokia 720 mobile phone at your nokia care, iron bridge allaphuzha -688011.
on 17-8-18 .

they have said that they will get it within a week or 10 days but still i they have not got the display, but the the amaziang thing is there is nobody in the office to give the status .
every time i go to the office they give me a no . it is difficult to get this no because always it is busy or out of range . if we get the no we get a reply that he will find out and call back. niether the call comes or the reply.

please take in some action . We had never expected this from a firm like NOKIA...
