DTDC Courier & Cargo — AWB:D83842779 not yet delivered

A parcel was booked on 27jan2022 being AWB:D83842779 from kolkata for the destination to Bangalore, But the same parcel is not yet delivered.On complaining twice on the customer care some one called yesterday on my mobile number and claimed that he has delivered the parcel and sent me a delivery sheet where a fake sign was done in the name of kaushal.He also mentioned over phone that he has delivered the parcel on 12thfeb 22. Where as I Was not present at home on 12th feb22, hence my signature on the delivery sheet is quite impossible.I am attaching the same delivery sheet sent to me on whats app as evidence of delivery.
Any one can identify that the signature and the person who has filled up the delivery sheet is the same person and his hand writing is same in the delivery sheet and at the place of signature of kaushal.
