Degrading behavior to potential customer

Had a very unpleasant customer services related matter at Village Square, Randfontein's Signature branch. Sunday morning the floor assistant young and tall, African lady was quick to point out that testers are to be used, yet on request there were none available. I was told they get ******. She offered to call he supervisor as I was flabbergasted as to how I should use something clearly pointed out to me , yet not available? She called her supervisor only to be informed that she was doing her banking at 9:30 in the morning. This would normally not irate me , but it was the arrogant manner and the way I was looked down on by this floor assistant, it bordered ******s. She addressed me in a derogatory manner and made me feel uncomfortable. I have a witness who can confirm to this incident. As along time customer it is saddened that one should be treated with such disdain.
