St Courier — I'm complaining about my damaged parcel

As I sent a pracel through st courier Chitlapakkam branch to Pudukkottai, my parcel got damaged . I called Chitlapakkam branch regarding this but no one replied . Then I contacted head office Pallavaram, they told to talk to Mr . purushottaman Chitlapakkam manager . He told not to register complaint and he will sort out the issue and have asked the details in head office . But now he is also not answering the call . Now the head office lady whom I spoke with is also telling we can't take complaint now .
