Harsh, unprofessional and potential ****** consultant

I just got a very harsh, unprofessional and potential ****** phone call from once of your capitec consultant who was very rude on the call. I had explained to the consultant that I am in a work meeting he insisted on speaking to me instead of requesting to call me later, he was so rude and impatient and kept on yelling at me and loosing his temper. This is such a sticking attitude coming from so called sophisticated banking. Train your employees to speak to customers professionally. Very disappointing. I am not sure why was he speaking to me they way he did was this because of my skin colour or what? Really ****ed off. Track your records and tell that consultant to apologize
