Folks who have this problem have multiple ways to solve this. Doing the age-old thing of calling customer care and brooding won't help. Use social media to get things done. My issue was resolved in less than 16 hours, the reason being the follow-up I do on the twitter feed of ACT BB,

Recently, the technical personnel of Reliance Wi-Max turned up at my apartment after I have surrendered my connection in Nov 2013. They were requesting me to return the PoE adapter and the antenna. Such is the customer care and follow-up of Reliance who claim to be the best ISP in India.
ACT BB seem to be doing a good job, although they need to improve their customer service if they want to retain the numero-uno status in Bengaluru.
