The only plausible inference, it seems, for my delayed reply, is that Wishnet is a very bad ISP.
Service - Decent. Much better than BSNL. Occasionally, or rather, rarely, some problems may arise.24 Hour Toll free provides support and keeps you updated via SMS . Local Cable Operator is in charge of cabling and related errors, some of them work fast, others may be a little lazy, but any problem you have gets fixed within a day or two.
Peering - Wishnet maintains a NAS which contains popular software cached, you can download stuff from there at your peering speed. Plus, if any Wishnet user is seeding a torrent you're downloading, you may get speeds upto 10 MB/s from that user for that torrent. Almost all popular torrents on kat.ph download at such speeds. This works even for DesiTorrents, but I can't confirm about other Private Trackers.
Yes you'll get 1mbps from 1AM-9AM, I downloaded 9GB when i had the 3mbps night plan, so you may get about 1 GB downloaded in that time
I currently have the 1 mbps night plan, i really don't download anything which is not peered. You'll get almost all popular stuff peered, you can share files among other users at 10 MB/s using a software called HFS ( Works like FTP Server, though its an HTTP File sharing software)
