DTDC Courier & Cargo — Product damage, misplaced,Rude behaviour

I am totally dissatisfied with the service.and the complaint is about the rude behaviour of your employees at Nagole branch.
I've sent the courier with experiment material from Bhimavaram to IICT tarnaka Hyderabad on 28/11/2020.and it was not delivered in the specified location and misplaced to PUNE Maharashtra.
Again I sent the courier from Bhimavaram to IICT tarnaka on 31/12/2020 and now the parcel is not delivered and it's at Nagole branch in damaged condition.(box was broken, material was wasted).on top of it your Employees are calling to the customer(who's has to receive the parcel at IICT) and talking very rude.he is a cheif SCIENTIST and your staff are so annoying to behave like this.
Because of your negligence item in my parcel got damaged and definitely I am expecting apologies and refund amount of rs.1000 for the damage.
Awaiting for you response ASAP.if not I am going to raise a consumer complaint on this issue legally.
