UNIT TRUST PAYOUT STILL BEING SORTED AFTER 3 YEARS - NOT!!

After trying to get my son's unit trusts paid out for 3 solid years, complaining, sitting for hours in enquiry qeues, emailing and seeing managers, FNB cannot seem to get the issue sorted. I have now been informed by the branch manager that I must just wait as they have done everything they can? I am sorry FNB but you made the stuff up coupling my son's account, opened in 1998, with a trust who is of no relation to our son, and the trust which was only registered in 2001. It is unacceptable that it takes so long for a simple payout to happen. Can NOBODY at FNB step up to the plate and deal with this issue? And you handle people's money? Scary!
