Tracking details - ru[protected]nl,
My parcel was to come from netherlands post international to india post morar h. O.
After the parcel was delivered to morar ho on 24-10-18. The postman milin kumar sharma delivered the parcel to wrong address i. E. G6/52 without calling or informing me.
For more than a month i did not even know about the parcel and i kept waiting that as it is coming from foreign it might be taking time.
But when i contacted the website in december they said it was delivered. It took time to get information from them about which courier service was involved.
Then when i found out in january i have been trying to retrieve the parcel from the wrong address and from the postman and now he says that it is his mistake but now what can he do about it.
Postman name - milin kumar sharma. Postman phone number - [protected]. My parcel was delivered to wrong address i. E g6/52, windsor hills, gwalior. I went there to receive my parcel but did not get.
So now i am complaining here. Please help we retrieve my parcel from g6/52, windsor hills, gwalior or help me get a refund of parcel.
