very humiliated

I was issued a cheque dated 16/10/15 I then went to fnb to cash up the cheque I found myself embarrassed and humiliated when I was told that the cheque was invalid and the banks teller repossessed the cheque like as if I stole the cheque I even heard the voice background as another teller instructions I shouldn't be given the cheque I just like to know if this is the procedure at fnb as for other banks they give you back the cheque or they write on the cheque refer to drawer I found it very much in apropriate the way I was treated
