DTDC Courier & Cargo — Rouge DTDC agent do not door deliver and warns 62 year old mother to pick it up

This is very consistent problem in our town. The DTDC agent who is supposed to deliver the package to the destination address would call and ask us to come to his place to pick the package instead of delivering it. When confronted about it he boasts to give complaint about it and the company officials can not do anything to him.
On July 13th he again refused to deliver the package to my mother who is 62 years older and after a lengthy phone call he budged and delivered to her but with a warning the next packages won’t be delivered. This has been happening in my area for past 10 years and DTDC officials deny the company name is not even Desk to Desk courier service..
