Discriminatory business practices

I just requested a quote for our car insure and we didnt get face and the consultant was very discriminatory to my marital status, I am currently living with a partner which I advised him at the beginning of the call and he felt the need to go fishing like I am under investigation, asking me weather my partner has paid Lobola are they negotiations happening how long have I lived him , they want to establish whether my relationship is serious or not of which I dont see the relevance and he was unable to explain too. If this is how they do business I am better off taking my business elsewhere if they going to discriminate on whether I am married or not and want to know the intimate details of my relationship. How is that relevant to car insurance if I am wrong please let me know but the intimate details of my relationship are not relevant to how we will pay for car Insurance.
