32 Day Interest Plus and 32 Day Flexi Notice with different interest rates?

I queried the so called #The Changeables FNB about my 32 Day Interest Plus saving account because I noticed the savings account is generating 1.5% interest less than FNB was advertising on their website. The feedback I received from FNB Investment was, “Sir, you 32 Day Interest Plus is an old type of savings account and was only generating 2% and indeed 1.5% less than new 32 Day Flexi notice.” They claim communication was sent to clients about closing all these old saving accounts but I was wondering how many accounts are still active with millions of Rand invested and FNB pocketing the 1.5%. If you have a “32 Day Interest Plus account” close it immediately.
