Cannot process international receipts

I receive international payments from time to time in to my business account - small amount (under R2000) once or twice a year. I never had problems receiving these funds before, until FNB have now decided to not process these transcations anymore - they send you an email, asking what the funds received are for and will then consider releasing your money.

How is one suppose to run a business if you have to explain minor transactions like this?

Further - there is no big follow up - I almost missed the email, if I did not go browse through my older non important mails I would have never seen this email from FNB and lost this money.

Back to the days of manual banking it seems.
