Hyundai Vredenburg service invoice

Warning I had my Hyundai H1 servised at Hyundai Vredenburg on 26 Nov 2021 When collecting, i was shocked by the invoice. I queried some of the ridiculous prices and quantities I was charged on the initial invoice. 10 units of Transmax fluid invoiced : R3945.60 (unit cost R394.56) and adjusted later to 5 units R955.00 (unit cost now R191.00) 13 units Anti freeze invoiced : R1597.44 (unit cost R122.88) and adjusted later to 5 units R955.00 (unit cost now R191.00) Some other items were also queried. When questioning the original invoice, i was informed that units were booked out for the service but not used. I just want to warn future customers to check their invoices.
