DTDC Courier & Cargo — Package Not Delivered - Invalid Reasons Provided

My package was supposed to be delivered on 14th and package contained sweets coming from Tirupati to Bangalore couriered on 12th.
DTDC guys I dont know what they have messed up, they are lying receiver is not available. I am very much at the given address neither there was any call attempt made nor anybody entered premises on apartment.
They are updating status as per their convince and not resolving my issue.
My courier is already spoiled and they are not ready to refund nor give resolution
Tracking Number - H73616378.
I have raised multiple concerns digitally and through call centers.
But none has helped me.
