Disgusting Call Centre experience with SANTS Private Higher Education Institution

Just had one of the most unprofessional experiences EVER. After speaking to lady at SANTS asking her information regarding age exemptions. She provides me with information that doesn't make any sense then after me explaining and asking a question for clarity (POLITELY) she just decided Shes done speaking to me hanging on the telephone for over 30mins. Kept on sighing and fidgeting on the other end and spoke to a colleague.This lady is extremely rude and her attitude needs to be addressed.
