a very rude call center agent

My brothers phone was ****** from him on the 5 April 2015 at Ahmed Kathryn a hospital in lenasia, I call In This Morning To BACKFLIP The Phone ,By That I Am On The Phone For An Hour Trying To Get Through To The Call Center After An Hour Sharon Answers The Phone, I tell her that my brother is in hospital undergoing AN operation I do not have the ime number, she tells me to go back to the store I bought the phone from I tell her that the store in 14th avenue is closed, she checks on the system and asks me when I bought the phone I tell her that in 2013 because I am due for an upgrade in October she says that Wat I am saying is incorrect, I admit I lost my temper and called her stupid then she drops the call in my ear,is this what you teach your call center agents to be rude, I want an apology,and another thing I have been sending emails about the network problem at home but no one is willing to help me,so mtn I am very very disappointed with the service I get from you
