The 27-year-old left-back joined the promoted Eagles on a free transfer from Bordeaux but has since only featured in the club's Capital One Cup exit at Bristol City.
It then transpired that the former France U21 international was not included in Ian Holloway's 25-man Premier League squad, meaning he cannot feature in the league until January at the earliest.
Marange does not understand why he was signed if he cannot play in the top flight.
"I'm disgusted," Marange told L'Equipe. "If I had known this rule, I would have a clause in my contract.
"But my advisor did not tell me and now I am told that it is basically my fault.
"We lost [at Bristol City] but I was not at fault for the two goals. I have only had seven or eight training sessions. How can you judge a player after 10 days?"
Marange says he has not been included by the club since penning his deal in South London and is already considering looking for a move in January.
The Frenchman claims he has effectively been ignored since signing midway through August, adding that the wage increase he received on leaving Bordeaux counts for little if he cannot play.
"I have never been presented to the press, I have never had an official photo and I am still waiting for my club suit.
"I stayed for 15 days in a hotel before finding somewhere to live and the club told me I had to pick up the bill.
"It is true, I have a proper contract, I earn a little more than Bordeaux but living in London is 10 times more expensive. And I came to play.
"Either I rip up my contract or I wait until the winter transfer window to find a club."
