Pathetic service

At first I was happy with the service from when I got a rental through my insurance after my car got written off. However after I took the car back and was told it'll be 5-7 days to get my deposit back, that is where things went from bad to worse. Calling after the 7 days I get told by the Milnerton branch they'll get back to me but that day and a weekend passes and I hear nothing. When I call back I get told that he must have gotten distracted and forgot to call me back. Then to be told it'll be 7-10 days. I let hay time pass and still nothing. I call back and get rid again they'll get back to me and again nothing. So I'm left having to call again. This time again I get nothing but told to email Client Services. So I do that and guess what... Besides for an automated email reply... Still nothing...
