Trai — unable to use 3g data

Sir i am a existing customers of bsnl. When i recently recharge my number with a pack of 429. Which has offering 1gb 3g data daily. After i recharge i found there is no network available for browsing the internet... Then i call customer care lodge a complaint... They were solve this problem... But still this matter is not solved... Like me there is many others who face the same problem... All money for this recharge goes in waste... Please take action against this type of frauding.
