Reliance Bigtv — reliance dth connection 05/03/2018

I booked 2 dth connection in march 2018. Despite numerous calls to customer care and mails i still haven't got the connection. The only reply i get is within a week you will get the connections installed. The customer id is [protected]. Till june i was getting sms regarding it will be done in 45 days but no updates after that and when i asked them to refund the money they said it's against compan's policy. Please look into the matter as soon as possible.
