Accident cause by Europcar hire client unresolved

On 12/06/2019 one of their clients Mr D C Roodt cause a 3 car accident, he except full responsibility for the accident. From that day I made numerous phone calls and visits at there offices in cape town where I was told that a Ms Ilsa Marius are handling the case. Up until today nobody of Europcar hire contacted me and my vehicle is still standing at the Panel shop waiting to be accessed by one of there agents. The people of Europcar don't come in contact they refuse to call back and they have very bad service in trying to resolve this accident damage that was caused by there client.
