Complaints on the issues were raised and after chasing many times technician comes look after for temporary resolution solves it a go stating no such problem will be faced again and again after a day or two same problem comes again have to follow the same procedure for resolution . On ** June I have dropped an email to their registered email id for disconnection till date no one has responded for my disconnection request.
