carried on with a cancelled repair quote

I am very upset with the service I received from Renault fountain, I called 3 minutes after I got a quote to connect back cables that were disconnected, because the call centre lady could not get hold of any one in the workshop, se promise that she will pass the massage and they will come back to me, after five minutes I called them again the same lady tried to transfer my call to the relevant people, and still they were not answering the phone and she promised me again that she will pass the massage , after 10mminutes the lady we were looking for called me back to say they are done with the repair and there is nothing they can do about it and there is nothing I can do about it, so I asked for the manager who said he will listen to the calls that I have made, after five hours the same lady called an tell me that the manager have to leave to somewhere, so still nothing we can do, I am not happy with that because if my transferred calls to the workshop were answered the time I called , nothing was going to be done, now I must pay for something I cancelled , im not happy at all
