Upgrade an extra GB or so bandwidth

[#1]

Is it possible to add an extra 1GB of bandwidth to my monthly usage for this month? I've so far already gone over my limit for this month by almost 25GB and I'm going to need an extra 1 or 2GB allowance to make it through to the end of the month.

Assuming you are on a current product then unfortunately no - you could cap your spend and run the rest of the month at very slow speed
