Perhaps they are just structuring the plan in such a way that people tend to opt for longer duration plans thereby guaranteeing that they would be connected for that many months. Also they would get to raise immediate funds.how does anything change by charging for
36 months in one go? they are taking 3K (2K is refundable though i assume?) at the time of connection installation. so it's not like people would get connected. use it for one month. and then stop renewing! this would only happen if they know that their services are going to such so much that people would not renew after one month lol.
I myself opted for the 3 month plan, cause the installation was free and was planning to switch to the monthly plan after the 3 months got over, now I would definitely stick with the 3 month plan for how much ever time they allow me to.
