Misleading information and delay on customer enquiry

My mother was looking to purchase a new car and I referred her to Barons Woodmead as I had bought my car in January, I also did this as I was advised by Ronald, sales exec that I would get a referral money if my mom purchases a car. And so she did, I have been waiting for over a month since my mother purchased a car from Amandla at new sales for her 2022 T-cross and have been getting the run around. I am simply unhappy with the communication and would like the referral money to be given to me as the sale was completed in early March.
