Poor customer service ever

Good day I had a very bad customer experience with one of the business representatives by the name of Rudy Naidoo. I have a business of which I wanted to buy cash batteries for Sabat or Willard because I have customers who are interested in buying. Rudy came to my shop we spoke and he promised to send an email the following day of which he never did. I went an extra mile to contact him via watsapp and calls. He ignored my texts and my calls until I asked to use someone’s phone that’s when he answered. He gave him a piece of his mind after that I received an email stating that my application was declined due to useless reasons. I wanted to buy for cash as a new business woman to empower myself but I don’t know what was his reasons to give me such poor service. I don’t know whether is it because im a woman and the color of my skin hence bad treatment. I’m hoping someone matured and reasonably can be able to assist me as I’m still willing to buy batteries
