Poor service

On Thursday 2018-03-29 at 18:33 i hired a vehicle at Europcar. I was given a beige polo vivo-sedan. The coloured guys who was asisting me with the vehicle told me that it was dark so the vehicle could not be inspected. I went to the vehicle by myself and on arriving to the vehicle i was assisted by a guy with my bags into the car. I also did not inspect the car but from the airport i went to my flat in Cotswold then after i went to Grahamstown. When i arrived in Grahamstown my brother noticed that the drivers wheel cap was missing. The following morning 2018-03-30 i called Europcar to inform them of the missing wheelcap the guy that i spoke with told me he will make a note and someone will get back to me. I never recieved a call. On Sunday 2018-04-01 i returned the car and i asked the lady that assisted me if i can view the footage that shows the vehicle when i took it and she said she doesn't have access to view it i should wait for the supervisor. On Thursday 2018-04-05 i called Europcar asking about my refund and i was told that the refund has been processed and when i asked what is the feedback on the wheelcap the guy said he will get the supervisor to call me. The supervisor then called me she said she will view the footage and send it to me. On Saterday 2018-04-07 i called since the supervisor has not got back to me and no one has updated me about what is the way forward. I spoke with Siyo and he told me that on the system it shows that i have been charged for the wheelcap and a cracked screen (this was new to my ears as he was telling me) and when i asked him when did they see a cracked screen and why did they not inform me about this he said he will get the supervisor to call me on Monday. I feel that i was ill treated and i feel like i am the only one who has to bother myself about the process for the people at europcar they are quiet they do not call
