Bad Agent service

I had made arrangements on the 18/05/2023 with agent Bontle to revivew a unit, I was going to take for the 01/06/2023. The agreed viewing date was to be on the 20/05/2023 @ 7:30. Bontle never showed up, ignored my calls and whatsapp messages which was utterly unprofessional and disrespectfull. She did not have the comom courtesy to inform me prior of a reschedule or anything, just utter unprofessionalism on her side.
