The Professional Couriers claim to be the largest Courier/Logistics/Warehousing company in India (in their phone caller tune). Regrettable experiences that I had with them were (not just a few) - their complete lack of understanding of the concept of speedy deliveries for which a customer uses a Courier company - loss of packages/Important documents/mis-routing are rampant. Their Regional Customer Service at Bangalore does not even pick up the calls made to her; and their Operations Head sitting at Navi Mumbai - himself is helpless and openly curses his team for their incompetence. Finally it is the customers who are the sufferers - no redressal is given to the customer.
