Hi am not happy at all SMD bloem asked me to pay R1500 for the towing of my car and I did that then they turn around and ask for another R300 for cancelation fee because they gave me a wrong amount it was meant to be R3000 for towing. I paid the R300 to get the R1500 refund. I still haven't received it. I just want to sell my car
