Nedbank Foreign Currency Account

I opened a FCA (Foreign Currency Acc) with Nedbank. On their website it clearly states that this is an interest bearing acc. Well I have had €100 in the account for around 6 months and have yet to receive a cent 's interest. I brought this to the attention of Nedbank on the 11th January via there Facebook page. Client Services has referred me to my branch, I have called the call center and there have been emails back and forth apologizing for the delayed response. STILL no one has explained WHY i am not earning interest. Its like no one knows what is going on there or how to handle the inquiry.
