The Professional Couriers — Non delivery of parcel and rude staff

I had booked a courier from Chennai to Bangalore and the consignment number is PRO12143611. The parcel reached Bangalore. However, the delivery staff who brought the parcel refused to deliver it to the apartment, stating that the person has to come downstairs to the Main Gate of the Apartment Complex to receive it. The attitude and conduct of the delivery staff was extremely rude and even on being told that it was impossible for the receiver to come down to the gate as he is a senior citizen and cannot walk properly, he refused to go to the apartment and instead immediately said that the parcel will be sent back to Chennai. I am extremely upset and disappointed as that parcel contained medicines for my father who is a senior citizen. Please make sure that the parcel is delivered as has been paid for. The delivery is meant to be made to the door. Not to the apartment gate.
