Bad service

I went to Standard Bank Eerste River to get some of my investment money loose. I went straight to the teller as advised by the branch manager a few months ago. When i got to the teller she advised me that i must go to the other side cause she cant help me there. I then argued and explained but this is the third time coming here for the same thing and both previous times ive been helped by the teller. The teller very rude then told me but theres nothing she can do. I then requested to speak to the branch manager. The branch manager then came and acknowledge that she told me a few months ago to go straight to the teller but the teller cant help me now and i must go to the other side. I then asked the branch manager but why must i go there and she rep**** to say i should go to that side first and then they will send me to the teller. The last time i was there i went straight to the teller and i was helped so what makes it different now. This branch is really a problem. My first time visiting the same branch i went to open a funeral policy. i also got send from pillar to post as only 1 person works with funeral policies. this is not right so you as a client must then sit and wait for that one person to be available to be helped. I dont want to put my feed by this branch ever again.
