[Resolved]  BSNL — Not getting the desired speed in Bsnl Broadband

Hi.i am from bangalore.from 2 weeks i am experiencing very low internet speed.My BSNL broadband plan is 500C. I called up at call center and told about my problem but they are not giving any responses. I am getting the download speed of just 50Kb/s which is much less then 500C people should get. Means speed will vary between 250 to 280Kb/s.

Again i called up at call center...they told me to check the SNR margin... and told that you SNR margin is very low and "LINEMAN" will come and check the line...but they are just not coming. wat shoul i do now?
