DHL Express India — yet to deliver my consignment with awb no - [protected]

Address:

560066

Hi, i had sent a consignment to china via dhl express with awb no - [protected]. I have made the entire payment and the promised delivery was 4th of august. I was not formed with proper details by dhl at the time of sending the consignment. The consignment is stuck with customs in china and neither they are delivering the consignment nor delivering it back to india. I've sent multiple mails regarding this to the dhl customer care but for no response. Following is the extract from the mail i sent to dhl.
1) i was told that i should have collected a customs clearance form before entering china for these goods. But i was not informed by dhl on the same while shipping my consignment from india. I was informed that my consignment will be picked from my house in india and will be delivered to my address in china within a week, which didn't happen.
2) i was told here by china dhl that personal goods should have value of less than 1000 rmb, while my consignment is valued at 3600 rmb. So they advised to go via agent. But the agent charges around 2000 rmb which is almost double the shipping cost. When i was told by dhl at the time of shipping that the amount paid was full and final settlement, expecting me to pay again double the amount again to get my consignment delivered is not fare. If i'm paying multiple times why will i take a professional service from dhl?
3) the china dhl person has conveyed to my colleague that even if we go through agent i can't get it delivered because there is a pressure cooker in it. I gave the list of items i'm carrying in the consignment and i closed the box in front of the dhl representative before he picked up my consignment for delivery. Why was i not informed at first place in india, if i can't carry items which is not allowed.
4) the china dhl person has conveyed to my colleague that even i can't send it back to india as there are few items like knife, shoe polish and soap in it. Again why is this confusion. If these items are not allowed why was i not informed before sending the consignment.
5) i need my goods either delivered to my china address or return it back to india to the given address in my previous mail. I'm not ready to pay anything extra as i have already made my full and final payment in india for the consignment and it is dhl's responsibility to deliver my consignment to me at any cost.
6) if both can't be done i need a compensation from dhl for the value of goods and i need a refund for the amount paid towards my consignment to dhl.
