Address: 4-5-16/3/1, Vegivari chavidi street, Kovvuru, 534350

Hi Team,

I have a package with tracking number H82281081 with DTDC, it reached my nearest hub on JAN 2nd and not yet delivered to me, I have sent email to thier customer support and called customer care, they investigated and responded today saying that package is missing in the transit, They have also asked me to provide the content inside package and proof of payment and I provided, there were 3 sarees in the package and package is of worth 2800, when I asked them to refund the amout from DTDC, thier cutomer support response is very rude, they are saying u have not paid money to DTDC and have no right to demand for refund, they are asking seller to contact booking office, I have made a online purchase and package is misplaced by DTDC, how come seller will rome around thier office for this, Seller has siggiiped package using DTDC and shared tracking number to me and thier job is done, And the cost I paid to seller included courier charges also, I want full refund and compensation from DTDC.
