Customer services agent in Centurion, remove her

I got bad and *********** service from Lee in your Centurion Mall branch in Customer services. Last Friday i came to change my cellphone number. she didnt do it. i still received smses to the old cell number i went back again on Tuesday 5 june, i saw her making copies behind their work area while i was first in line. they were only 2 agents at the time the other one was busy with a customer, she looked at me and went to the back for a long time, a queue started forming behind me we stood for about 10-15 minutes she eventually returned with a bottle of water and sat down, no smile no friendliness just looking like a tall statue. i told her that she didnt change my cell i even confirmed with the call centre, she just asked me about my vehicle finance and i said my business acc she sat there typing for a long time then she said did u get an sms, luckily i had both numbers, i checked my new number( shes not telling me which number , cos she doesnt care) , i said i didnt, she continues typing , i decided to check my other phone i see an smses saying bye to notifyme or something i told her she keeps quiet, i then left,no apology no nothing just like that......pls remove her from dealing with customers who bring business to ur bank. i dont want to deal with her
