Send Expired items to customers

I ordered KN95 face masks for a specific time senstive purpose. I received the masks yesterday (31 Oct 2022) but noticed that the masks have expired - they expired 20 April 2022. I have logged the return, including the picture of the expiry date. Their answer is a ... we're sorry.. our suppliers messed up. It will take two/three days to collect and process the return and then we will log a request to have you refunded. We cannot replace as we first need to access the return and then only order from alternative supplier, which means the delivery can take place only after that. We're sorry you are left without a usable product but we will refund you in due course. Effectively making their problem mine. No "Can we perhaps provide you with a suitable alternative from our current stock and make an effort to get it to you on time." Just.. we're kinda sorry we f@cked up.. have a nice day.. we hope you find what you need in time and somewhere else. Your cheque is in the mail.
