St Courier — Late delivery, inappropriate answers by delivery boy

Address:

Dwaraka nagar, Visakhapatnam

I ordered some materials in Instagram and they dispatched it through st courier and gave me a tracking number.. After few days, it shows out for delivery with contact boy number... And I called him, he said I am full of orders today, so I'll deliver it tomorrow.. As a human, I understand this.. And next day again I called him in the morning, he said I'll deliver by today night.. So, I cancelled my meeting and waiting in home, bcoz it's important delivery.. After 8, I called him he said it will delivery tomorrow and cut my call.. Even after I called him so many times, he is purposely rejecting my call
