DTDC Courier — Non delivery of items / no intimation

I had ordered a product through ebay and the seller had shipped the item through DTDC courier. When I track the item, it has already been received at the delivery location couple of days ago. However, there was no intimation or delivery of the product by the local delivery office. I had similar experiences before and I had to go and collect the packages myself from the local office. Date shipped from Delhi: 11/09/2015 Date received at local delivery office (Alwaye) : 15/09/2015 Ref no: Z62874996 I called up the office today (17/09/2015) and I was asked to collect the same from the office. Aren't we paying the courier company for delivering the products at the designated address ? My address is well within the delivery area.
