Rude and unprofessional telephone consultant

I was just phoned by a sales consultant named Mohammed who wanted to introduce me to the Vuka Hospital Plan. I told him nicely that I am not interested for I do have a medical aid and I am a housewife without any income. Before even giving me a chance to finish my sentence the guy sarcastically laughed and said "I see you are broke I will phone you next month when you have money," and then he put the phone down in my ear. According to me, he was extremely rude and arrogant. I will never encourage anybody to do business with a company with people like that doing their telephonic introductions to their products.
