DTDC Courier & Cargo — Fraudulent looting of money

I want to raise a complaint on dtdc for the poor customer service, no mails are replied and no one attended from customer care.
1st of all the estimation was not shared to me at all, they have done wrong calculation and the amount came till 14000 inr but my weight is not more than 15kgs, i was not shared any details on estimation. I myself called and asked and they are looting money i knew and i told them to cancel it they agreed and said they have told already to stop. But they have not stopped it and it has reached destination hub. Clearing it’s a fraud activity. Please help me. It’s a big amount and it’s not calculated properly, they said they have stopped and when i asked them about tracking they said sorry we have moved to destination already then i myself checked with my tracking id it was still in source only. But today morning only it has reached destination hub. They could have clearly stopped it but all this done to loot money. Person who is talking to me is not obedient
