DTDC Courier & Cargo — courier not delivered and very offensive response

Address:

Coimbatore, Tamil Nadu, 641035

I have placed my courier on june 6th 2018 in dtdc courier saravanampatti, near kaalapatti pirivu. They promised me to deliver my courier next day. We have called post two days from the date of courier. They said they will deliver the next day. This answer last for one week and their response was same. I had to followup daily on this where as it's their primary responsibility to give us an update incase of any failure. Today i called them and their response was offensive and they said us to get back the courier as they doesnt have service to kanyakumari. My question is, these people doesn't know whether they have service to their courier? These people made me tense and also made me wait for more than a week. Then i manually asked those courier person atleast to hold the package and spend my money, traveled to nodel point and got my courier.
If money was their (Dtdc) motive, then am sure they will fall soon.. Very frustrating experience with dtdc. I dont know where to raise this as complaint. But need justice on this irresponsible behavior of this courier service.
