Ea ingame purchase scam

i clicked on a 100 dollar pack and it sent me to a 20 dollar transaction and forcing the payment along with not allowing me to spend a hundered dollars even though i have suffiecent funds seems like ea is more concerns keeps the audience from obaining ingame items for hours and refusing purchases because ea cant keep up. this is a serious issue and needs to be addressed. this makes me not want to support ea with my ingame transactions if they cannot work also would like a refund of the 20 dollar
