Dishonesty and non honor of agreement.

I would like to be assisted with regards to a sales person by the name Malusi Vimbani of Hatfield Vw. We had been in communication in the past 3-4 months as he was assisting me getting a vehicle. I had made him aware of all my financial standings with the means to have him get me the best deal. He had told me he would assist at a fee that had accumulated to R4250 for him to make the car deal pass. I had since made him aware that I want to retract the deal as I felt that I am taken advantage out of being desperate. He has now blocked me and refuses to have me refunded. His cellphone number is ***.
