Hero Motocorp — Headlight of my bike Glamour has not been working since 25 Nov 2029

Address:

MONGOLD, Khair Aligarh UP 202138

I bought my bike in March 2019 and in only less than 2 years the headlight of my bike is not working. I went to nearby Hero Motorcorp Service Agency MonGold at Khair, Aligarh UP (202138) for not working of Headlight of Bike.
They said there is requirement of some part which will come by 10th December 2020 but till now they haven't brought. Due to not working of Headlight it is very difficult to drive bike in evening.
Please make it available the spare parts whatsoever at agency as soon as possible.
