[Resolved]  IN2CABLE INDIA LTD(in2net) — less Broadband speed and frequent disconnection

i am using 384kbps night unlimited plan which starts from 9pm to 9am. and on Sunday 24hrs.
according to 84kbps speed my download speed should be 48kbps. but i never get this speed rather a max speed of 34kbps that too only after 11.30pm approximately. from 9pm to 11.30 or 12pm i hardly get speed of 10-15kps that too frequently my download stop in between and i have to again download the file from starting many times.
i even complained about this problem but no solution yet.
