Useless Europcar

I collected a Swift on 22 March 2018 OR Tambo to be returned25 March. On route to my residence in PTA I realised the car had mechanical problems and reported it to their call centre. It was promised that car will be replaced by Pta branch 09h00 next morning. Didnt happen. Couldnt use car. Reported matter 12 x times to call centre. Left the car(which was a risk to drive)at their Pta branch on Sunday morning which was closed. Uber to airport cost me R480. Reported matter once again to unprofessional attendant and left keys with him. They collected car on Monday and charged me full charge plus one day....
