Nedbank Deliberate Failure to Release Funds

We have funds coming from oversees. Yet when we cleared it with Nedbank they promised it will be paid over Tuesday...never happened. Called them and they said Wednesday and TEAM LEADER assured me funds would be paid over this day...never happened. Called Thursday and long story about maintenance/back end issues etc etc Most cumbersome/tiring bank with more forms/red tape to get things done than the other banks
