Account linked not resolved.

I have my homeloan and mfc on my money app. Now I can only see my mfc account. After 35min on the phone and downloading the app again the guy says it's my fault the accounts are not linked. But it was there last week and gone this week. Now I'm told I must go stand in the queue at the bank again. With my fica also struggling because they say it's done but still getting emails.
