Nine times in ten the validity is counted from the date of issue instead of from the bid closing date. The requirement is in ITB 19.1 of the bidding document, and the system now checks it while you prepare.
Nothing can be done. The closing hour is enforced by the system clock shown in the header, and no account in the country can accept a late bid. Submit early and resubmit if you improve it.
Yes, until the closing hour. Submit again; only the last submission counts. After the closing hour, no.
Sessions end after 20 idle minutes, and an upload in progress counts as idle on some connections. What you had saved is kept. Upload large files one at a time.
That is a fraud. No fee of any kind is paid to any person for a tender on this system, and no official will ever telephone you about one. Report it to the help desk with the number that called you.
