Meghbela Broadband — Slow downloading speed

Address: Kolkata, West Bengal

I am a customer of PMPL broadband since 3 months, I was using torrent with much seeds and at a speed o[censored]p to 2 mbps and sometime 10 mbps. My package is N1_jet silver economy, from 16th may suddenly my torrent download speed came down to 50-60kBps on high seeding torrent. I don't know why this is happening, I changed my torrent client, I unplug and then replug the LAN cable but nothing happens please fix this problem ASAP. Thankyou.
