Black Opal Liquid Foundation from Clicks Nozzle doesnt work

I have recently bought the Black Opal True Perfecting Liquid Foundation and for the 3rd time now the nozzle doesnt seem to work. I end up having to open from the bottom in order to utilise it. It is such a pity that it has been my foundation for years and cannot change it. but its so painfull as well having to endure what Im getting. I have the 3 containers with me still.
