Elica — Built in microwave oven

Address:

New Delhi, Delhi, 110024

I had lodged a complaint on 4 Jan 17 for turntable not rotating in Microwave oven.
Complaint no 279896
On 6 Jan 17 technician visited and left stating that the motor needs to be changed which will take 3-4 days.
I have called customer care on 14, 15 & 16 Jan to be told everyone that a call back will be arranged.
Nothing has happened so far.
Please expedite the repairs as such attitude shows such a highly reputed company in poor light.
