I have booked and appointment with clicks Atterbury clinic for baby immunization, confirmed with clicks booking department about state stock was informed that they have stock. When i drive to the store the following day i am informed that there is no stock , The Nurse was just rude about it, acted like he doesn’t care. The customer service at clicks is poor, not even apology for the inconvenience caused.
