Hathway Cable & Datacom — refund

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

Due to corona virus, everyone is working from home. My company also provided wfh with instructions to have a good internet connection. I was looking for a provider who could provide internet within a day. When i called hathway sales guy, he committed that hathway can do this. He assured me that internet will start working within an hour of post installation. It's day three now and i'm still waiting for internet to work.
I had to recharge my other wi-fi device since i had no option. I called that sales guy multiple times and every-time he came up with a new explanation of why it's not working but never provided the genuine reason.
I called other technical persons too, sent messages and there was a same explanation from everyone that it's a technical issue.
Now, no one is responding now.
Not even helpline number where you wait for half an hour in queue and finally gall gets disconnected.
Installation was done on 19th of this month. It's not really a good experience for a new customer.

Now i don't need hathway broadband connection. I just need help for a smooth process of refund which is not happening.
Since the internet never worked for me, i haven't used a single kb of data.
I'm attaching a copy of payment receipt.
