[Resolved]  The Professional Couriers — parcel not received but website shows delivered to? some other area

I had sent parcel through professional courier service on 30.06.2021, bearing consignment no: MAA[protected].The track website shows the parcel is delivered but the recipient has not recieved any parcel.
I have been calling the booking station- who said parcel is delivered talk to customer care, customer care is telling the same thing that parcel has been delivered and hence closed my complaint, on explaining that the parcel has not received by the recepient and probable wrong delivery, she said she will find out and after a day, on calling again, she gave a telephone number saying he is incharge of Bangalore distribution, which nobody is picking, I have been calling several times to the distributor s number but he is not picking up the phone.
The customer care lady says they will not track our parcel, I have to track the parcel by talking to someone who does not even pick call. From past 1week there has been no effort to track the parcel or its delivery to the recipient from professional courier team.
