I have recharged my idea number [protected] on 18th september 2015 with amount of Rs 699, which gives me unlimited access to internet for 28 days at 3G speed. But after recharge i received 3G speed only for 3 days and after that it goes to 2G speed or more worser than that. i complained customer care but they told that i would receive speed only upto 40kbps (which is less than 2G speed) since i have utilized more than 3.5Gb of data and this is their limit. i was surprised by their conditions. During checking for best fit recharge no such issue was told by the company in detail also. i constantly mailed them and their customer team too assured me that they will look through the issue. But since i have waited for more than a week and my plan is about to expire in 15 more days, no positive result about 3g speed is being solved. hence i have raised the issue. Kindly give me 3g benefit for the remaining period which is left. The company didn't mentioned 3.5Gb data speed breaker condition at that time of recharge which is now corrected and is being shown nowadays. i am sending the screen shot of the recharge offers which i got on my phone. i want either 3g speed or half of my recharge money which ever is possible.
