Terrible service

Every single time I go to collect western union from ABSA Waterfall mall in Rustenburg I have an issue, first I got discriminate against because I'm *** then the woman had no idea what proof of residency I could use and again today I got told by the teller be quiet I am talking I am not helping you with this proof or address go get another one" we have been using this proof or address everytime I have collected and have been helped with it, now as I'm standing here there is apparently an error that she doesn't know how to fix. Please can somebody sort this staff out they don't know their job.
