POOR service and fail to refund

I regret renting a car from Europcar Harrismith; the inspection report showed a dent on the left rear bumper, and now they say that I scratched the same bumper and under the car. I paid to cover such occurrences, but they still refuse to give my refund, claiming that I must wait 21 days working. Nathi Sithole (Lady) was assisting but was too hurry to conduct an inspection. I really do not recommend using this branch because they do not interact; you will be the one phoning.
