Very Bad Service from Outsurance

My car was bumped by an outsurance client at the back while it was standing still at a Parking outside Pick n Pay in Fish Hoek 25/05/2018. This Gentleman then gave me his details and i went to open an accident report at Fish Hoek Police station. following days i contacted the gentleman then he gave me a ref number ( ********** 73) for me to follow up with his insurance which is outsurance. They requested documents and pictures from me which i comp**** and then i was told the process normally takes 4 to 6 weeks. During the period i kept on calling asking about an update, none of their stuff phoned me to update me about the incident which i find it as a very bad service. I'm still trying to get my vehicle sorted out, outsurance keeps telling me they trying to get hold of their client while my car is still not fixed as from the 25/05/2018 till today 26/07/2018. Why am i the one suffering here when their client is not responding to calls and messages. This is a very bad service from outsurance i don't know how many people they doing this to and i dont know if i'm the only one who is experiencing this frustrating service.
