Terrible Service

About 3 months ago I've send in my car at Citroen George and till this day my car is still in for service.This are the reasons why I am unsatisfied with your service and demand a answer. They said my car will be done in the first week ,then the week after They did not call me at all to come and collect my car !! I had to contact them at least 3 times that week ! To get answers and got nothing !! I Called them they said they need to order a battery ,so I just asked why is it so expensive and they rep**** rudely to me ! I felt mistreated ! After a week NO REPLY again I drove all the way from Oudtshoorn to George with my own expenses and asked the managers number which they refused to give . I asked if I can maybe use a courtesy car and they said no.( I feel its a big service the least they can do is help me out) After a week I called again then they told me the mechanic is on leave ,SO NO COMMUNICATION once again + No one was working on my car that whole week ! They said a week after they must maybe order a new part but did not ask my approval !! I have no car for 3 MONTHS and don't know when to expect my car back. I expect that this will be sorted out with the head office of Citroen.
