India Post — courier received with missing items

Dear sir/mam,
Courier number:-cc[protected]nl
My cousin sent parcel on 9 september 2017 from netherland. I received it after one month on 9 october 2017 with missing items. Parcel contains some baby products like oil, clothes, baby bag etc. When he sent parcel, the weight was 7 kg but when i received it was less than 5 kg and is was in very bad condition and also it was in open condition. I am requesting you pls enquiry about my parcel. I am expecting best results from you.

Regards,
Sukhwinder
