Credit Card Security code wrong?? Unable to sign in without it...

Hi! Basically, I want to remove my card from my current Apple account, but I'm unable to sign in on the account in order to do that, because it asks for my credit card security code and then claims it's wrong... I already contacted Apple support through the chat system, but now I would need to call them (well, we actually scheduled for them to call me), and I would really like to fix this issue quickly, and especially without talking to someone on the phone. I have social anxiety and the issue is not that important anyway, because I cancelled the card today (due to someone from China making a purchase on my old Apple account 🤦‍♂️ luckily I might be getting a refund). Anyone got a fix for this dumb problem? I found another post and people were telling them to sign in to iTunes to change their payment method, but I can't even sign in anywhere (I tried on Apple TV and iTunes, but both tell me to update my account on account.appleid.com where I wuld need a valid credt card security code)... Oh and I do not own any Apple products, I only made this account for Apple TV on my PS5... Which is where I'm currenly logged in still. Thank you!
