China Tourist Visa in Singapore was rejected.

Hi, I am a Philippine national saying in Singapore under student visa. I would be going to China on the 20th Dec. for tourism purposes. I applied for the visa in CVASC here in SG sometime this week and they outright rejected my application stating that I can only apply earliest a month before intended travel. Can somebody confirm this for me? Or am I being played by those in CVASC? Thank you.
