So angry and dissapointed

I am so disapointed and ****ed by FNB's services,yesterday i went to do a query,on the 26 i deposited the money to Capfin after a day they started calling me that the have not rercieved my payment and already i've throw the deposit slip,so i went to the branch on Monday and waited 2 hours to get helped and gave up and left for work,i went again yesterday and got there at around 11:00 i waited and waited on the que untill 14:00 the line was moving so slow,when i got inside i explained to the teller,she just told me to write the details about the deposit,she will check for me,i did and she left me there,she started being busy forgeting that she's attending me,i was very late at work yesterday for nothing because she never came back to assist me,then i left. This is unacceptable,honestly.what do i do now? I can't always go to FNB without getting help,this is serious
