I am on plan 590Nu, i was configured on 512 kbps downstream initially, though i used to get 32 KBps constant. Now 2 days back, the MTNL suckers downgraded me to 256 kbps....and rendered my connnection non funtional for 2 days. Now though the connection is running I am getting around 28 KBps.Can u guys suggest whom to contact in Delhi for restoring speed to 288 kbps, so that i may get 32 KBps speedShud I contact 1504, GM BB office or Mr. Shubendu???????
