Standard Bank - Moneygram Section - Kimberly main branch : Pathetic

I went into Standard Bank main Branch in Kimberly town for a moneygram transaction on 24 March 2018. A Mr Empraem was very slow in serving customers. Everyone in the line was complaining. On raising this complaint he indicated that he would not serve me and he didnt like my attitude. I told him that he has no right not to serve me just because l had complained. I requested to see his superior/ manager. On duty was Idah Mokhemisa. She did indicate that Empraem did not have a right not to serve me and informed security to convey this message to him. This was done but Empraem continued to serve other customers behind me. He even asked security to take me off the banking hall. I went back to the manager and requested a private meeting. She initially refused indicating she was manning reception and had noone to leave. After some time she then agreed. She requested me to write my complaint on a piece of paper. I did exactly that and requested a meeting with Emphraem 's manager. She indicated that he would be in touch with me on 26/03/18. Noone contacted me re this. I find it very odd that a standard bank employee has a right to refuse to serve a client purely because the client complained about poor services being rendered.
