Poor Service

My claim is not paid out since 10 February 2015. Service consultant is Deslyn Narayan, his service has been extremely poor throughout my engagement with him. He is always busy to attend to my case. He does not have time because he deals with so many other important clients if not busy with IT guys fixing his machine. He has never returned my call. only time he responds by email when I call to follow up. he could not answer my questions to my satisfaction. He is only paying out 21% of my original claim based on his reverse case of 1960s.
