Missing Invoice That I Have Tried To Get - Booking.com

I booked a stay at Blankenbaker Inn in Louisville, KY via Booking.com for the dates 08/18/26 to 08/20/26 and I now urgently need an invoice for this stay for work purposes. Despite this being a very simple request, I have not been able to obtain any invoice at all. I have contacted both Booking.com customer service and the hotel multiple times, but I keep getting the runaround from both sides and no one actually issues the invoice. This has caused me a lot of frustration and is affecting my ability to complete my work-related reimbursement. I request that an invoice for the total amount of 178.88 for this stay be issued and emailed to me as soon as possible so I can use it for my work documentation.
