I keep going on 'Job centre plus' looking for work and they are taking the mick- what can I do?

Employment agencies are parasites they shouldn't be allowed to use the services of the job centre unless there is a real job, i don't know about Britain but in Ireland they advertise "jobs" with the EU symbol beside the advert meaning locals not wanted and somehow they get away with it legally even though its discrimination. When the economic migrants piss off home you'll have the upperhand because they'll be desperate for workers.
