St Courier — Not delivering the parcel to door step

For each and every time I have to reach St courier office to collect my parcel which is 8km far from my house, delivery person is not even reaching my door step to deliver the order simply he will reach the landmark which i have given and asking me to collect the parcel at times and when ask him to deliver at door step they are showing their face anfld refusing, am completely annoyed and disappointed why am i paying waste of Rs 80 as a delivery charge when i have to reach the office to collect the parcel and at times delivery person will wait at some place and he asked me to reach him to collect my parcel.
