DHL Express India — Rude behavior of DHL EXPRESS clearance team

For my shipment DHL arranged a call back. Before my queries could be resolved they disconnected the phone. Very rude and unprofessional behavior this is. I am asked to pay Rupees 2000 as penalty. I have already approved for that but I still need the clarification for further processing. This shipment is sitting in Bangalore for over 2 weeks and I have still not received by shipment.. I don't know how much more delay will be happening. no resolution to this problem. Please help resolve this issue at the earliest.
