Iam giving 1star as there is no option of giving negative stars. If that option is available, they should get a score of negative 10. All cheaters. They make very sweet promises at the time of selling but never keep up their promises. They dont care the customers. They made us to spend about 2 lacs for the product and hardware and stopped attending the concerns. Basic features works fine but any specific feature we ask, they do not care. The features are available even for 15-20k in the market. All cheaters.
