Very very very terrible service

After taking my hyundai i20 for a 15000km 1st service, I also had to repair or replace breakpads under maintenance plan with Capital, buy their employee name Liberty refused said I must pay for the breaks which then gave me the amount of +-R1200 . I couldn't do it immediately, I in fact went further to other dealer in Bryanston where I was advised that breaks are covered under maintenance plan ... and as I was been taken from pillar to post for this repair the car end up being on metal to metal until it slipped and being involved in an accident damaged back door. ..after numerous occasions the manager then eventually agreed to put new breaks and disc as it was already damaged, but they refused to fix the door and went for other services like at 30000 km different problems including the ignition that wasn't turning and at first i was told by Straighdom Park employee that was an anti hijack, ignition doesn't lock, but I went back again as it was constantly locking. I booked the car and was there more than 7 days with only 1 phone call I received from them and I had to time and a time do follow up and after more than 7 days they requested me to bring the spare key and they fixed the ignition and I cannot use the other key as it's spoiled and I can only use the spare key and I must make myself a copy for other key .All this was under warranty but I was told to cut other copy myself and few months later i am still stuck with the same ignition problem which the new manager is refusing to help me and my car is still under warranty on 67000 km. ..and he unequivocally told me I must make other people /Hyundai employees their mistakes his mistake and that he wasn't there .He blantantly said it in my face said I can go anywhere to complain that is not his mistake and that I can still call Hyundai South Africa head office ... please Peter help me, my car is there and the man is not at anyways helping
