Unprofessional conduct, pathetic service

We used this Au Pair agency in Cape Town called Sitters 4 U.

This Bianca is incredibly rude, she throws the phone doen in my ear while I am talking. She wants to have payment upfront and doesn't want to refund when she can not provide an Au Pair of our requirements on the required day. She freely insults clients as she pleases. She has no manners
