My no is 8796884020. I have 1p per second billing plan for STD. Earlier i didn't realize but later found out that i was being billed at a rate higner than 1p/sec. When i called customer care i was told that the rate was applicable only for first 10,000 seconds. After that i will be charged at 2p/sec. This was nowhere written in the agreement at the time of taking sim. Also when we see online, the site doesn't point out such charges. This is a way to cheat the customer by keeping hidden charges
