I have sent emails to sales manager and sent to FNT(finance lady) who also dint bother responding that's why am here, both of them dint even bother to respond,i bought a pre-owed 2021 hyudai atos from hyudai boksburg with atos last month it's only 1 month and few days driving this car it just stopped while i was driving in the middle of the road which is the worst experience for me since it's my first car, and the car alarm keeps going off anytime so many times, I complained I was told to bring it back and they fixed the issue but on the day stopped working the alarm started again going off, which hyudai lenesia said the problem it's the alarm system that was installed, what is frausting me is month end absa will debit for a car I dint drive this month, this happend last week Tues today is day 8 I don't see any action form them, my car was towed to Hyundai lenesia where the guys there tried their best to fix my car, but they couldn't couldn't act further without consent from hyudai boksburg dearlership, I was told my car will be towed to boksburg Monday since service department don't work weekend,.only today 19 of October Hyundai lenesia called me to tell me my car was only towed today by boksburg team which the was no communication whatsoever from them, they are just quiet am so frustrated I even wish to cancel my contract with them. I regret going to hyudai boksburg they lack good customer service. Hyundai boksburg has not even called me not even once to update me what will happen or what is the way forward am very disappointed.i feel like I was sold a problematic car and now they are acting very slow with my case.
