Kejora Masyhur Sdn Bhd — wrongly wrote plate number of bus trip

Address: 68100

I suppose to take the bus to sp @ 12n on 8/11/2019. The receiver @ the counter wrote the no plate of the bus behind the ticket n ask me to wait at pltfrom 12. I wait untill 12.30n and no bus no that had written arrived. I go to the counter n ask about the delay n they told me that the bus trip @ 12n had make a move. I just want to know why must wrote the plate no n the plate no is totally wrong. Its so confusing for the new passenger like me.
