Bad service from Webuycars Silver Lakes

I bought a trailer for Silver Lakes in April 2022. Paid R1600 for for roadworthy, license and registration as informed by the sales person. They only registered the trailer. Now in September 2022 the license disk expired and when I renewed it, I was told there is a roadworthy certificate outstanding and the license is in arrears. When asking the branch to assist, they just told me I needed to do roadworthy and licensing my self. This is the worst service I have ever had when buy from a dealer and my second bad service received from the Silver Lakes Branch
