FNB Worst service imaginable

I have experienced the worst service from FNB today.I have tried to lodge a serious dispute with the FNB Life service via phone and e-mail. After staying on the line for over an hour at a time, there was still no answer to my call. I've tried to email to the address provided via the phone service and which is stated on the website but it comes back with a message that they are unable to reply to any emails. It is the worst and most frustrating service ever!
