Worst network even in heart of metro city. Review on Tikona WiBro

One of my friend recommended me the tikona wifi conection because its plan rates were cheaper than any other internet service provider. So I decided to install it and done the same. Tikona's engineer visited my house and installed it on next day. I have paid around 2200 for first 2 months(includes installation). After third month my bill was around 750+. But the worst thing of this internet is that from the next day of installation it started taking so much time to appear a login page and you have to login each and every time when you start your pc or laptop. Most of the time when I really need the internet then it was not working. The customer care says it will take upto 24 hrs for connection. So what I will do if I need internet right now and they are providing connection on next and even next day internet not available. You have to complain again and again. the engineer visited my home just rotates the wifi device directions and says its one and as he goes again internet get disconnected. So if you have to do important work related to internet you can not rely on it. The speed of internet is also so worst even in non peak hours.
