Den Networks — dd national channel not visible during cricket match

Address:

422101

During cricket match between india & newzealand on 22nd oct 2017 dd national channel on den network is not visible. When i asked about this no satisfactory feedback given by the operator. Kindly resolve my complaint.
However during monthly payout of cable fees no such information given to consumer. It is simly missleading to us. It happened during last cricket match between ind vs au's. Thanks
