Hathway Cable & Datacom — amount not refunded nor giving any response to mails

Address:

Hyderabad, Andhra Pradesh, 500039

Hi,
I have applied for the new connection in peerzadiguda, hyderabad and paid amount: 3, 179/- on 19th feb 2019.
And i received a/c no [protected].
But same day evening technician called me and said that there no feasibility in my location to provide service so he said that he will process for the cancellation.
And next day (20/02/2019) i got confirmation msg stating that due to technical reasons we were unable to process your request for new connection. And refund will be happened within 15 days.
From last 4 days i am trying to contact customer support through mails and phone call but no one care to provide the status details.
Why you only shows interest in getting new connections and when you fail to give connection due to your technical issues, why don’t you people don’t respond.

I just want to know when will my i receive refund.
Did i done mistake by opting hathway broadband??

Regards,
