FNB InContact Email System not Working Properly and countless hours wasted

The email function of FNB payments is heavily delayed from around 6 months ago. I have spent countless hours trying to resolve this with FNB Technical but I only receive trivial feedback like remove your IN-Contact recipient and add it again. Other banks I bank with email notification is received within 1 or 2 minutes on any EFT's that banks into my business account. FNB sometimes takes 2 hours for these emails and delay is NOT on GMAIL Side or my email server side since other banks emails received immediately. I rely on this email system to ensure my staff receives payments banked to release stock and now I get calls every day when a customer waits instore trying to pickup something of which he did a FNB to FNB Payment and staff does not receive email on EFT banked. This is extremely frustrating and costing me private time and interruptions. Fix you email system for InContact banked EFT's. It has been a issue for 6 months and due to this reason I will move my account to another bank if not resolved soon. ABSA and Capitec does not have an issue or delays and emails received immediately.
