Recruitment utterly unprofesional

Last week I was called by Mr. Athenkosi Nyengane for a position at the Riversdale branch. He said I will need to go for the assessment and this was scheduled for the 10th of September, he said he will email me more information and until today I have not received anything. I phoned him after several attempts of making contact from which I've never received any response either. When I did get hold of him we agreed to the assessment on the 5th of September at the Riversdale branch and that I will shortly receive an sms as confirmation, this I never received either. I have send a FB message to Capitec which just keeps telling me that the matter has been referred to HR and that they are waiting for feedback. I phoned Athenkosi again this morning, and now all of a sudden he couldn't tell me when the assessment would take place and where it would be held. This is such unprofessional ethic for a company that apparently strives to be the best in the industry!!
