Appalling customer service

After eight long years of trying to change my e-mail address and getting a monthly statement from Sentinel I finally made contact. Your consultant Felicity is obnoxious at the least. Telling me the industry number I gave omitted a digit? Then to have the audacity to tell me not to scream. I am wondering perhaps she suffers from a hearing impediment? Seeing one moment see can not hear and next she has over lee sensitive hearing? Needless to say I have not received my statement. The service is appalling, Contact center a hold of seven minutes! From 2008 that I HAD to join the fund I had not a single favorable experience.
