The answer is simple - be like that California woman (see http://www.theregister.co.uk/2016/06/27/woman_microsoft_windows_10_upgrades/) and take them to the small claims tribunal where they are prohibited from sending along a lawyer (but make sure their representative has no legal training because you can be fairly sure that they will try that trick if they think they can get away with it).
You are then on equal footing with one of their sales droid and in front of an judge who only has to decide on whether the "patch" was fit for purpose
