No knowledge of procedure

I went in to a Capitec bank branch and deposited a cheque. I was advised of when the cheque would clear and went on my way. I then went on to a different branch before the cheque was cleared and was advised of the same clearing date. 3 days after the clearing day stipulated by 2 different employees in 2 different branches, I was told that it has not been cleared and no one knows why and they can't get hold of anyone to advise.
