CALL CENTER INEFFICIENT

Call center to change a procedure date to a later date (after having received authorisation previously) took 16 minutes and 53 seconds! Initial choices on calling their 0860 # does not provide for authorisations...get transferred from department to department. I originally made the booking (obo), agent then had to call for confirmation to authorise me to make the changes and then transferred me to a different department, who transferred me to a different department, then autoprompter asked for medical aid no, then got through to someone who then asked if it was for me, went through explanation again, he advised he would add me on as a "temporary" contact, and then assisted. Such an unnecessarily frustrating and costly (0860 # are share call numbers) experience.
