St Courier — Irresponsible staffs

Address:

Chennai Velachery vijayanagar

Hi team,
I have received multiple items from st courier services. But they have never delivered the item on time. Even if the status is out for delivery, they will take one more day to deliver the same. If we call them to get the response, they are so rude and switching off the phone. It's really unhappy to hear if someone says that i have couriered in ST courier. Chennai Velachery staffs are so lame and lazy. Please put the staffs who are customer friendly and deliver the product on time.
