I am disgusted by the pathetic service

All I need and asked for is that the rental is extended until I get my car back as there are more problems with the car and they now need another week for that, which I assume would be longer, as well as affective communication for discovery. This whole situation has brought me no joy at all and I am at a point where I don't want to listen to anyone anymore cause no one can assist, I think that going the ombudsman route will help as I know my CPA right as a customer and are disgusted by the service I have received so far, the rental need to be back tomorrow how that is going to happen I don't know. I did speak to Sharleen today, the team leader, who told me that she will have to escalate this matter to her manger regarding the rental and she will provide me with feedback latest today 3pm which I cannot wait till then cause what must I do now as this car need to be back tomorrow 17 March, I need feedback now. I have done what I was supposed to do, I checked up on them almost every day which they the only say they will come back to, then I had to phone them back every time. And now there are a lot of things wrong with my car, I want feedback and I want my car in a good condition....
