Franch Express Courier — Not delivering courier for past 6 days

I have couriered on 02/12/2021 on tambaram branch franch express. Deliver address belongs to mylaudy (po) kanyakumari (dt). While posting the courier i dont have the mobile number of receiver so the girl in tambaram branch said you get the number and inform us by call..after one hour I called tambaram branch to update the receiver mob number they didn't picked up tried many times but they didn't picked up single time...while checking the status it shows it was sended to nagercoil hub next day...from that day I am trying to contact the delivery boy for atleast 30 times not even one time he attended our call...we mentioned address clearly but they not event went to that address...that receiver waiting for past five days.. seems thay just skipped that parcel and saying simply and irresponsibly that there was no contact number..! That delivery address was in main road itself...atleast they should attend our call or else they should call back to the sender number. That is emergency parcel..please ask them to deliver by atlest tomorrow (09/12/2021). Consignment number [protected]
