Chaos Theory Retro Pack

I was going to buy the Chaos Theory Retro Packs to 24/24 to be rewarded with the Bangalore heirloom set. I bought the Apex Coins i thought was enough to be able to buy the apex packs till 24/24 which would've given me the heirloom. After i bought one pack the pack pricing went from 300 Apex Coins to 500 Apex Coins per pack. It didn't say anywhere that the pricing would increase by buying more packs. I now have lost 60€ i can't afford to lose and i feel like i got scammed. Getting a refund would most likely mean id get the money into my Steam Account but i don't have any use for the money on Steam. I would prefer to get my current Apex Coins removed from my account and to be given the heirloom i thought i was going to get for the money i put into the game. I've now gone through EA Support and i got told to post about this on EA Forums. I really hope i can get help through here to get some satisfaction. I feel like i now lost my money🙁
