It's surprisingly easy, just time-involved, to sue large corporations in small claims, at least in some jurisdictions. Yes, they've got lawyers, but if you have a case you may still win. I sued one of the largest telecoms in Canada for not honouring a verbal contract, and won quite easily once I proved the facts in dispute. Businesses assume people won't have the commitment to carry through and actually take them to court over malfeasance. Probably mostly correctly. I'm not sure it was really worth the hassle.
