Bad service from owner of Total garage Mimosa Mall Bloemfontein

On 20/07/2020 I bought petrol 93 at Total garage in Bloemfontein Mimosa mall. Somehow there was diesel in the petrol. I took my car back the next morning @07:15 after I experienced a lot of trouble, and the manager Palesa handled the situation very calmly and said I'm the third car coming back. Palesa took my details and ask me to leave my car at the station to drained the petrol/diesel and fix my car. I left for work waiting to hear from her. I told her I need to have my car at 16:00.

At 15:00 when I phoned Palesa. She said my car will be ready before 17:00. I'm a single mom and need to pick up my daughter from school at 16:00. Palesa said she will phone G6 services and phone me back. Almost immediately I received a call from the Total garage owner, (Amed - ***) and he was so so so rude! He demand that I'll wait until 17:00 form my car. When I start explain to him my situation he silent me and address me as: "my dear" in a rude way and angry tone in his voice. I said to him "I'm not your dear". He said "O, sorry for you!".

I hung up the phone and called G6 services myself.

Is this acceptable for a owner of a garage who made a mistake to put diesel in a petrol car to speak in such a manner to a women? Does Total accept this behavior? Why didn't he phone me earlier so I could made another plan?

I insist an answer! and apology! Why should I as a women accept such treatment from a business owner? It is unacceptable.
