Bad service delivery

Hi, my car broke down in the parking area next to CITROEN's workshop in Port Elizabeth on 2015-11-23. I battled 4 hours to get some response out of them. With major effort the car was booked in and I was told that the parts was ordered and that it will take 3 weeks and that my car will be ready by 2015-12-17. On the mentioned date I went to CITROEN just to find out that my car is not finished and that the parts was only ordered on 2015-12-02 and that the car will be finished on 2015-12-28. On numerous times I phone CITROEN S.A laying complaints about the matter with no response or different excuses. Up to now I am still waiting for the car and the last excuse was that the parts may be at CUSTOMS. Not very sure just a my be. In the meanwhile I am sitting without a car losing income from private work and my wife must walk 6 km a day to her work and back. I must always keep on phoning to be updated. I do not know what to do further. Even the mechanic who work on the car said I must lay a complaint by you. I even wanted to complain at the Ombudsman but they are closed. Citroen S.A said that I can register a complain by Hallo Peter and the Ombudsman they don't care. Thank you.
