Total and their F** ups!!

i went to a total Garage in Orlando east to fill transmission oil to my car,upon that I was greeted by a guy who assisted but unfortunately poured the oil in the wrong filter. he poured transmission oil on my brake fluid tank therefore putting myself and a four month old that I was driving with in danger. I was not aware of this as I a woman and I do not know how these things work. last night we went and laid a complaint where we were assisted by Thabang wo said he was the manager. he advised it would have to be drained and new brake fluid would be put in, this discussion took more than an hour and as I was driving with my baby again I decided to leave and we agreed I would come back this morning. when I went in this morning I was advised to leave my car and someone would drop it off this never happened, my brother had to fetch my car and drive back to park may I add he cannot drive and doesn't have a drivers lic. my cars safety was jeopardised, my safety driving with a car with transmission oil on the brake fluid was compromised and the only thing I was offered was for it to be drained?? I was inconvenienced and had to use taxis to work with no reimbur*****t. I need this sorted
