DTDC Courier & Cargo — missing an item in my courier

Address:

500081

I have sent a courier (H[protected] from dtdc booking office gachibowli to brand eyes customer care noida. Below are the content details 1) skullcandy ink'd wireless bluetooth earbuds (With box) (Worth rs 4000) 2) warranty document provided by brandeyes customer care 3) invoice of the earphones (Proof of purchase) the booking officer naveen asked me to pay for secure package delivery and insurance which is around 700 rs. I refused it and asked him to send a normal delivery (170 rs) and asked them to deliver the package safely. I have been tracking the shipment daily. One day i saw the status as receiver refused delivery. I have contacted brand eyes customer care and they told me that no once came to deliver the courier and the statement from dtdc office is false as their courier receiving office is open24x7. I have contacted dtdc noida regarding this issue. After couple of days they accepted that the product was lost and asked me to contact customer support so that they will initiate the refund. I have reached out to customer support regarding this and they told me to go to the booking officer. I visited the office and asked naveen about this. He replied me that since i have not opted for secure delivery and insurance the product was lost and he can't do anything about it and asked me to contact customer support again. After visiting him couple of days he called gachibowli manager venkat. Venkat told me that these kind of things are common in dtdc and since i have not opted for insurance they will not refund the amount. He also told me to file a complaint anywhere (Police station or court) i can because it is the company policy and they will not refund the amount. He also suggested me to stop wasting my time and forget about the product. On monday, my courier returned to gachibowli from noida and it contained only the documents inside it. The courier was not in the same condition at the time of booking. Please provide me a solution for this.
