I booked Tata sky bing plus connection as on 26/05/2021 Rs 2772.. But I requested to cancel.. As details provided by representative of Tata sky was wrong.. As been told the bing plus box can be connected to any TV but technician told it cannot be connected to ctr TV and told us to request for cancellation.. Regarding I applied cancellation request as on 28/05/2021 but till I not got refund.. Regarding I contacted Tata sky customer care but told to contact person with whom you deal Regarding new connection.. But the agent is not responding.. +[protected] damodar reddy mandapati
