The Professional Couriers — Parcel not home deliveries

The professional courier service at Birur town, Chikamgalur district, karnataka.(577116) is not doing there job, they asks customer to collect parcel where they specify, and if we dosnt agree thy say they will return it. This is how thy behave with customers. And in phone thy use arrogance talks and worst behaviour. If this continues comapny wil not get business. I want professional couriering company to take action against above mentiond adress manager. And change whole team n train them for good behaviour. And i want to get notified the same. Thank you.
