Booke and Partners Chartered Accountants interview questions

Had a interview on the 10th & the woman I met was lovely to speak to, she let me know that she'd get back to me on either the 14 or the 15th being the latest on their decision I never heard back, I called twice with no answer & left her a message and still not a word back. I don't mind not getting the job, my issue is the ghosting as it's not only just unprofessional but rude as well. I'd rather get a rejection email than nothing.
