The Professional Couriers — employee behaviour and not picking up the calls

Worst courier services i've ever seen. Just because company name is professional the employs won't be professionals. Train your employs that how to behave with customers otherwise that will be leads to damage your company. Careless employs. I request not to select professional courier it's waste of your time and money. Even one star is more for their services i'm not willing to give even one star also but it won't accept if i don't give rating.
