Apex Coins Not Received

I am pretty frustrated right now as i have purchased about 140 dollars worth of apex coins and didn't receive the 120 dollars worth. I have been going back and forth with ea for 10 days and after having tried everything there answer at the end was we cant give you your coins back. I have made the purchase on steam on this entire process has been extremely difficult and honestly i recommend nobody buy apex coins from steam since ea apparently cant do anything about it despite showing so many screenshots of email confirmations, steam purchase history and just about everything clearly showing i didn't receive my apex coins. At this point it feels like I'm being cheated and i don't know what to do. If i were to ask for a refund through steam will my account be banned even though ea said that there is nothing they can do to give me my coins that i  paid for?
