Hi zazarb, per our discussion over private message, I am posting here in your thread.

I would like to kindly request for an extension as there was a family emergency that came up and I had to take care of it and I can not pay you by December 31. Please allow me another month to pay you by January 31, 2023 and if we can maintain the payment at 0.605 BTC.

Thank you and very much appreciated for your kind consideration.

Dabs
