Query: Watch out!

I bought this MP3 player about 2 months ago and I thought it was alright until my volume went out. The volume button on the side will not allow me to decrease in volume. It still works, but only if you want to listen to it at a volume level of 50! I emailed RCA about the problem because I am currently out of the U.S., but they replied that they only deal with warranty issues over the phone. Their customer service online isn't very helpful. So now I just wasted $130 on something that I was only able to use for 2 months!! Be careful if you are planning on buying this product!!
