What is a reasonable response time for a response on an escalation?

[Richard1470]

We maintain a strict cancellation policy.  On December 7 a guest cancelled a reservation for the period December 11-13.  It was not an extenuating reason.  An AirBNB Support Ambassador got involved and on December 9, 2020 seized our money for the booking and refunded 100% of the guests money.  We asked to escalate the issue and were told to wait 48 - 72 hours for a response.  Despite reaching out to AirBNB on December 134, 20, & 21, 2020, we received no response.  On December 21, 2020, we mailed a Notice of Dispute to CSC Lawyers Incorporating Service, 2710 Gateway Oaks Drive, Suite 150N, Sacramento, California 95833.  To date we have not received a response from CSC Lawyers..

Anybody have a similar situation with no responses?
