You have got it all wrong my friend. The billing and then recovery agents calling and people going through hell is not really any ISPs intention and I know that for a fact. It is purely business and they are not out there to harras people. These companies including Tikona are in the market to get business and not scare people away for ever. I have been on and off with different service providers and experiences have been good and bad and at times these recovery people have tried things but this is not a perfect world and things like these will happen no matter what company you deal with.
You just have to know how to deal with these people that is all and it surely does not involve getting stressed which is clearly the case with you. These recovery calls are intended to scare you and they are having the intended effect on you.. are they not?
Tikona is not a fly by nite ISP and they are here to stay if you ask me. Some of the best business houses have invested in the company for example Goldman sachs has a stake besides some others. It is not an evil empire like some people make it look like. If you are getting a call from one of the recovery agents just tell them to write to you and not call as you wont negotiate over the phone. Get them to write a letter to you... I can assure you that letter would never arrive if the dues are not legitimate.
About Tikona's technology.. Fortunately I was involved in the initial days when the company was setting up and I was working for an American wireless equipment manufacturer who sold them a lot of hardware so I know how it all works. I cannot really explain everything in a reply here but be assured it is no less secure then a wired connection or a 3G connection. It is safer then your home router. Using a free frequency does not make them any less secure. Crack it if you can and let me know how far you got with it... It is not a cable tv ka cable that you can hook into at will or an electricity cable where you put a "desi kundi"
Your technology source needs to do a reality check before making tall claims.
