Airbnb Charged My Card $3 for "Invalid Card" Errors

I was trying to make a reservation, and after entering my credit card details, they immediately charged my card $1 without even asking for a password! Then, when I tried again, they charged another $1. I switched to a different card, and they charged another $1 from that one too, bringing the total to $3 deducted from my accounts.

After all these charges, I then received an error message saying my "card is not valid"! This is outrageous. If the card isn't valid, why are you deducting $1 for verification? This makes absolutely no sense and feels like a deceptive practice to steal money through bogus "verification" attempts.

Airbnb, you need to rectify this immediately! I demand a full refund of the $3 that was unjustly taken from my cards. Stop these unauthorized charges and provide a clear, functional payment system.
