Is Wilgeheuwel Dentist not open, working or what - don't answer phone

Crown came out & tried booking an online appointment which is a waste of time because it does not show available dates & times. Just tried calling & selected option 2 & no answer. This is so unprofessional. According to the website they are open. Tried making an appointment a while back & also no answer. The only reason I continue to support them is because of the actual dentist, Jess, otherwise I would have gone elsewhere a long time ago
