Unrealiable people what work with the sales of Vehicle!

I bay a Nissan NP200 1.5 dci Bakkie on 6 Sept 2022 and while I am waiting for my bank to approve the loan on 7th September 2022, when I phone them to tell them my loan is approve and then he told me he have sold it to a adder person! This is ********* to make a promise what you are not kept!
