Four days back signal not available occurred in my d2h.. So i contacted and lodged the complaint for the same with d2h customer care. Next day their engineer visited our place but misbehaved and went without solvong the problem.in the meantime. Videocon d2h deducted 200 rs from my account as their service charge.
My problem is still persisting. But they are not taking any actions still yet.
They have deducted money from my d2h account without any reason and without any information.
