I had speedpost an important parcel on 9 march 2019 from mukherjee nagar post office 110009 to leh ladakh 194101. It’s been 20 days my parcel is not delivered yet. I registered complaint on 16 march but they didn’t do anything about it. It shows current status pending. I contact my respective post office they said they had send my parcel on 9 march and they can do nothing about it. I ask them to help me and they were really rude to me. Please help me it’s very an important parcel.
