Bharat Sanchar Nigam [BSNL] — Bsnl 3g internet speed

Address:	691583

I am using bsnl 3g internet. It's showing very poor connection speed. They say that the maximum speed is 500 kbps, but i am getting very low speed about average 20-60 kbps. I have already informed many time on there customer complaint helpline. But there is any progress on the speed it is same as before. Please do something. I have recharged about rs 333. But i can't use it. Plz do something. The bsnl customer care is very bad. Responce and problems clearing is not good
