Super bad customer service

I had an encounter when with Khayelitsha super spar. I was harassed my a security person and they claimed they have suspended the person. The MD of spar saw that i was not worthy to be to be contacted by him after he could not reach me on my cell phone twice. He refered a third party to contact me, being the security company. I sent him an email asking why would they do that because I was a customer at spar and i do not recall shopping at the secirity services. After I sent an email with a complaint the MD contacted me to meet, and requested us to meet. We met and said i should name my expectations. I did so and he said he had a wedding to attend he will get back to me after three working days andI should be glad that he as an MD took the matter in his hands. I wonder where did he obtain his degree for serving people as an MD. When I got at Spar he said I should retell the story after I have over an email, and he would conduct an investigation. My question was , how do they suspend a person without an investigation and how did they live the matter to lie around for over a week without investigation after several email were sent between us. I regret not taking full audio recording of that meeting but I do have for the last minutes of the meeting.
