Extremely rude estate agent

I was looking to rent a unit in Linden and tried to get hold of the letting agent Carina van der Linde, she didnt answer her cell phone (which is acceptable considering estate agents are busy people) so I called their office number and asked if I could possibly speak to another agent who could aid me in my enquiry. Carina answered the phone at the office and was extremely rude to me, saying 'ive just moved a tenant in for the last two hours!!' she treated me like dirt on the floor. I strongly advise that people in the Linden area seek help from other estate agencies because Linprop are clearly extremely unprofessional and rude. With the current economic climate you would think Linprop would emphasize client relations but clearly this is not a priority for them.
