Navata Road Transport — Forced charges and collection fee at pick up

Address:

Jammikunta, Navata Transport

We booked a delivery (D062291) through a supplier based in Mumbai, fully paid by the supplier (who on-charged us). The delivery was supposed to be pick up by us with no further charges, from Jammikunta.
Navatha at Jammikunta has further charged us money for lifting goods to our vehicle - we didn't need or ask or for that matter require this as we were perfectly manned to perform this task. It was 4 pieces of articles, easily carried by one person,
The Transport agent threatened us with withholding goods and we had no option than to pay for the 'corrupt practice'. We are not happy about forced charges on customers that is 'unaccounted'.
