FNB SHARE SAVER STOLE MY MONEY

I Share Saver on the app but I can't seem to understand why i don't have any access or control on the account last Friday my money disappeared from the account without any notice of transaction. I cant see anything or any movements i cant withdraw neither close this account i dont have anything to conclude. I've tried calling the FNB hotline but it is a waste of time. From all i read online and on the Hellopeter site with this FNB Share Saver investment Im very insecure to continue with it. NO GROWTH, NO CONTROL ONLY SCARY STORIES OF LOSS AND BROKERIES *****ING THE MONEY. Please FNB with respect due to you i want to close and withdraw my money from Share Saver as soon ASAP. People don't trust this investment account
