Airbnb - No Payments - No assistance

I am a host at AirBnb, I loaded my payment method just to be notified 10 days later that the payment method is invalid. I reloaded the payment method, received one payment on that payment method. Since then which was in March I have not received one payment. Contacting the Customer/Help Centre does not work, all they do is tell you to reload your payment method just to wait another 10 days to be notified that the payment method is invalid. I am at a lost on how to proceed, Airbnb now owes me over R30k. Booking.com and Lekkeslaap - no issues with payment. This is such an unpleasant and time wasting experience trying to deal with Airbnb. I will appreciate advise from other hosts that had the same experience.
