Hathway — Refund still pending

Account no. [protected], name- parvinder singh, mobile- [protected], city- new delhi. I booked new connection wih executive named “kapil singh” of vikaspuri, new delhi on 29th sep and paid rs 4514 (6 months advance ). Due to personal issues and change in circumstances, i called executive and requested him to canel the booking and refund amount. I can confirm no installation has been done at my home and i notified exevutive to cancel new connection booking before installation. I am still waiting for my refund of rs 4514. I have sent several emails and executive is not answering my calls and is giving me no response with regards to my refund. Please process my pending refund amount
