Manager treats client like a dog

So, after going to seek assistance from Capitec Bank Waverley Plaza in Pretoria I have decided to leave Capitec Bank. A guy with the name Francois at this Bank have no idea how to speak to clients face to face. Me as a Capitec Bank account holder for the last 11 years, was just told that he can not assist due to certain reasons and turned around and walked away, like he was speaking to a dog. Not willing to take any further questions. I would think that he is a manager or some kind of senior as the teller called him over after the teller could not assist me with the questions I had. If this is the way he handles clients, face to face, who knows how he treats his staff.

Thanks Capitec for 11 years worth of banking, but I am done now.

Goodbye
