worst courier company DTDC

I BOOKED A PARCEL FROM KALIGHAT DTDC ON 28TH OCT. TO DELIVER IT AT KOLKATA 700 127. BUT MY PACKAGE IS STILL STUCK AT RAJARHAT OR CHINARPARK LOCATION. NOT GETTING ANY SOLUTION BUT WHEN I DID MY RESEARCH I GOT A NUMBER FROM GOOGLE OF DTDC CHINARPARK JUST TO ASK IF THEY HAVE THIS PACKAGE OR NOT AND THIS PERSON STARTED TALKING RUBBISH OVER THE PHONE AND LITERALLY SHOUTING, I ASKED HIM TO REMOVE HIS NUMBER FROM GOOGLE IF U DONT WNT PPL TO CALL U OR IF U CNT HLP THM HE SAID THIS IS WRONG NUMBER ND ETC , DTDC CHINAR PARK IS WORSE. CUSTOMER SERVICE IS WORSE.
