Stopped working on second use

This product sounds amazing - it adds volume and bounce to fine hair.... And it did - on the first use - but when I came to use it a second time the aerosol failed to work and no amount of trying would get it to work , I did attempt to run the spray nozzle under hot water, but still nothing!! I now have a full can of product and no way of getting the product out of the can - I did try to contact Charles Worthington about the issue but they failed to respond to my correspondence - so poor customer service too.
