Everyweek they stop there service. When i call there customer care after complaing they start giving service again.
But this time on 13 july i call them that wifi is not working. They took my complain and gave me complain no. From that day till today they say on call that they will resolve problem in 24 hr. But they dont make resovle our problem.
Now from yesterday when i speak to there head about problem and he promised me that technision will visit. But nobody came on visit to see wifi. When i tried calling them they dont receive call and nobody came front to talk. I told them i have work on net. To use net pls resolve the problem. They dont understand anything. And just avoiding things. And now they even dont receive my calls. Pls help me out.
