Hi All,I have a 899 Rs unlimited plan. In June 2010, the speed was increased to 512kbps. Things were fine for the last 6 months. Yesterday, my speed was restricted to 256 kbps. On inquiring I was told by Airtel customer care that there is an FUP of 10GB on this plan and has been effective since the speed was increased in June. I am pretty sure that this was not the case since I was downloading close to 30 GB per month and there was never any drop in speed. Also, while taking the connection I was clearly told that there is no FUP and we will give a speed of 512 Kbps.Has any one faced a similar problem? Speaking to customer care is not making any difference. Any suggestions?
