Yes, they dont know other than money. If you forgot to add your rate-cutters, your mobile balance will be next to zero. It doesnt mean they are transparent, none of the rate cutters will let you know whats the available balance sec/min/money you have; all it tells is the deduction details.
If you recharge for any amount more than rs.30, direct deduction of rs.30 will be done. To get the details about the deduction, you should at-least an year to get connected to the customer support. Again, they deduct amount for every 3mins.
Internet..! thank God they dont have the 3G network, if it would have been there, you should call can bank for personal loan. The 2G pack they provide is that awesome, you send a message thru any social network site to your friend, he/she will receive the next week for sure. Before that you might have visited him 2-3 times personally
By the time you take your monthly bill and check the amount you recharged, it you be close to your monthly home emi amount.The only advantage I see network. That gives me a reason to rate as 1.
