Worked with WIND for 3 years and have seen all the ups and downs. For a startup company it has come a long way. In terms of retail experience it was better than most other places. But there is still a long way to go in terms of improving the service, and the company realizes it too. The reason I left is that the money you get is not worth the complains you have to deal with from the customers about the service and network.
Customer complaints about service (they never end)
