St Courier — Courier not delivered and not intimate service not available in Bangalore

I never faced this kind of challenge in any Courier service. This is my first interaction with them, very worst and bad experience. I have sent courier to Bangalore (Metropolitan City), but without any intimation both receiver and sender, they returned my courier, they don't have no service respective location (Bangalore). ST Courier office (ENNORE, TN( [protected]) not informed me, service not available in respective location. Now, they returned our parcel and not return paid amount for courier. They said, You should be satisfy at least you get your courier, if loss what you will do. I never heard this kind of threaten any courier service.
