Hathway Cable & Datacom — refund

Address: Hyderabad, Andhra Pradesh, 560081

I asked for hathway connection on 31st march 2019. They weren't able to provide me connection because of some restrictions in my apartment so they said they will give the refund within 10 working days it's been one month i haven't got my refund back when i call their executives they say they are forwarding my request to billing team they will call u soon. But so far i haven't got any call. This is not acceptable. How long a person will wait for his money
