Abuse of a pregnant lady

I have had the worst experience ever with BMW rustenburg, Nkagiseng is the worst ever manager, or supervisor he wasn’t clear. He called to yell at me that the price that was given was a mistake for an offer for the car, that I didn’t make after struggling so much to get approval of the letter for the purchase from BMW SA finance. I’m a high risk pregnant lady who have been dismissed and my condition disregarded. This Nkagiseng said Gloria and Hein made a mistake about the pricing for the car but he calls to yell at me as if I was the one who made the mistake. Now because BMW SA finance has approved, he says he wasn’t aware of this. How is that my fault? Why should he insist on breaking my credit. Forcing my hand on a trade in when we agreed on a sell out? Utterly disappointed
