Horrible service

In November I bought a Renault Captur at this dealership, when I went to collect the vehicle the mags were scratched and bumper a bit loose in front and when I raised these concerns to the salesman he said not to worry they will take back the vehicle the following Monday which was 19 Nov to fix everything that was amiss, Monday came and went no feedback from the salesman when I would call him, he would say he wanted to check what's going on and will get back to me which never happened<I would call back myself and would get the run-around, to cut the story short I am still sitting with a vehicle that has scratches on the mags ,the bumper which he said was going to be fixed last week on Wednesday is still loose and he did not even have the decency to call me back with any feedback, I called the day Monday to find out if there was any feedback, he said he would call back, he never did, yesterday I called again he said he will call back still haven't heard a word from him, I have never received such horrible service ,this guy does not take clients seriously, I am Horrified with the kind of service I am getting (or rather not getting )from Multi franchise Tokai, a month later I am sitting with a problem that could have been resolved long time ago had this guy taken clients seriously.
