Hathway Cable & Datacom — worst service to get a connection - need the connection to be terminated and want money refund back

Address:

Hyderabad, Andhra Pradesh, 500032

I have opted for new connection 17th march, 2020, an agent called and have made me payment in an hour for 3 months package with 1736/- and informed the installation and connection will be done on the same day eod. But it has been 4 days, till now there is no installation happened. Also the billing has wrong name printed. She said she is going to change it and send me after i paid. Even there is no update on that. They just want to increase the no. Of connections payment happened through them.

They have provided me a customer care number, but its such a worst service that it only can ask for "new connection" or existing connection. My position is intermediate to this. I have paid for the new connection without receiving the installation. I have been calling the agent and customer care for last 2 days, eveyrday she tells that it will happen by eod and doesn't do anything after that. She says she has escalated but i don't receive a mail or update sms that there is something happened.
I can foresee how the service will be, so i have also asked for connection termination and to refund my money back. There is literally nothing to do with it right now. Today when we called the agent who made the payment and connection, is not receiving the call and messages in whatsapp to contact only through whatsapp and never replies.

Agent number who have provided the connection and promised to me about installation by eod on 17th march - [protected]
