St Courier — Poor performance of Tuticorin ST courier staff

The courier parcel (AWB NO [protected]sent from Coimbatore reaced in Tuticorin and the ST courier staff called my mobile instead of reachibg address, I could n't able to receive the call. Today I asked the person who has called me on yesterday and he did n't speak in a respect way and this guy (mobile: [protected]) speaking is not a service motive of your courier service. Please take action against him and such type of person will spoil your coueier's performance. Also I don't want to receive the pack please sent back to the sender's address.
