I am a guest that has been using Airbnb for the last 10 months. I have been at one place for some time now and back in April I added a new credit card so that all my payments could be routed through the new card. However, the payment method was not changed so I called to see what the issue was. I was informed upon calling that Airbnb charges the card that was used at the time of reservation and any change to a payment method for an exisiting reservation can only be changed by calling customer support. I did that and had no issue for May but come June they revert to charging my old credit card. Since my old card was actually a debit card and there were no funds in that account it pulled funds from the credit card because I used that as an overdraft protection. Now my credit card limit has been reached and the only message I get from Airbnb is you can try other payment methods. No acknowledgment of the fact it was a fault in their billing system. The customer service rep that chat with me also told me I had changed the payment method after this months billing when it was done 2 months ago and I told her to look through my past receipts. Now I am unable to pay my host until Airbnb sorts out my refund.
