Pathetic an unprofessional Service

I want to take this time to lay a complaint against a lady called Monique Cloete from RCS collections , firstly I'm very disappointed and disgusted in the service I have receiver from her , I called in the lady was very interruptive and rude , she actually laughed at me over the phone and when I asked to speak to her manager she refused to transfer me or hand over the call , I think that is extremely rude and unprofessional , she however provided me with her managers name Aneurin Kotze who gave me a call , I explained to him he will whoever listen to the call and get back to me but I informed him that I'm still going to report this case to HELLOPETER as I'm very upset about the PATHETIC call and UNPROFESSIONAL service
