RMB/FNB clearly not a fully fledged private banking solution

I am a RMB private client. Unfortunately, RMB onlt offers home loans through FNB. On the 31st of December the debit order for my home loan went off twice. This is already unacceptable. However, only the one amount showed on my loan account, so I thought - *****. I immediately reported it as ***** l, juat to be informed tharnit must have beem a system issue. This is not why I'm paying a premium for a private banking experience.
