Terrible service

AVIS hires a car out to someone who can hardly drive who bumped into me on the 16 Dec 2015, he he admitted fault and reported the accident with AVIS and gave them the accident report, case number my details as the 3rd party on the 17 Dec 2015 but nobody has bothered to contact me regarding the claim or accident, IS THIS HOW CARELESS YOU GUYS ARE? I have been going to your branches in Queenstown and i have been given a call center numbers after numbers and eventually spoke to Tembeka *** who promised to call back in a minute so i could check the REG number who did not, Monday the 25 Jan 2016 i spoke to Refiloe who promised to get her supervisor to call me back the following morning which did not happened IT JUST SEEMS NOBODY REALLY CARES ABOUT CUSTOMER SERVICE THERE and i need this sorted out asap, your client is running away from me and not taking my calls.
