Best Buy called yesterday

Can you believe they left a message on my machine that said that after careful inspection my camera's trouble is caused by corrosion and is not covered by the warranty. Hmm. I think that is interesting considering my camera worked fine until one day I took it to the beach and it probably got some sand in the moving parts of the lens. Why did I even bother with the warranty? So aggravating! Especially since my sister in law is going to have her baby any day now and I will not have a camera!!!
