British Airways Executive Club - No call-Centre response to urgent enquiry

Due to an unexpected medical procedure, I've had to postpone my return to London - I have been holding for over an hour on the phone to BA Executive Club to get assistance on how to deal with an uncertain departure date due to the nature of my current status - Wow, I am speechless, I assume they will use COVID as the excuse for the pathetic staff availability - Shocking service and this to a so-called potential revenue generating customer?????
