Compensation for Hyundai Service charges after Facebook Post A screenshot of the original Facebook post on Hyundai Australia's wall. A disgruntled Hyundai customer whose car servicing quote was inflated with unnecessary recommendations has received a formal apology from the manufacturer after venting her frustration on social media. She was also refunded the full cost of the service after complaining to the dealership. In a post on Hyundai Australia's Facebook page last Friday, Mali Hannun accused the Bartons Hyundai dealership in Brisbane of "deliberate fraud" after being quoted an additional $700 in recommended repairs for a standard $300 service. Hannun claimed the 105,000km service quote on her Hyundai i30 included about $400 in unnecessary repairs - including $83 for windscreen wiper inserts and $95 for a fluid flush. She said she confirmed the overcharging after contacting two separate mechanics for another opinion. Hannun's comments have attracted a fiery response on Facebook, with more than 35,000 people responding to her initial post. View original Facebook post here I went straight back to Hyundai and told the service manager the blatant rip off that had nearly occurred ... He squirmed in his seat for the duration of my rant and all he could offer me in way of explanation was that it may have been a 'typo' on the invoice," Hannun wrote in the post. Hyundai has accepted full responsibility over the incident, with a company spokesman telling Fairfax Media the inflated bill was a "genuine mistake." "The initial report from the dealer indicates that it was a ... a communication breakdown between the service advisor and the technician," the spokesman said. The franchise services up to 70 cars a day, so mistakes can happen. At this stage we're still working with the dealer to investigate how it happened. If there has been a breakdown in procedure or a failure of some sort, we'll work closely with the dealer to ensure nothing like it happens again. NSW Fair Trading has also encouraged Hannun to lodge a formal complaint over the incident, as there have been ongoing instances of overcharging at mechanical workshops. Since January last year, the agency has received more than 1800 complaints relating to car servicing and repairs. Last month, NSW Fair Trading detected eight non-compliant mechanical businesses during a raid of 16 premises in Kempsey. In three cases, fines totalling $1320 were issued to repairers due to an absence of tradesperson certificates or licences. Hannun, who did not reply to Fairfax Media's request for an interview, wrote in the post that she felt "completely outraged" and "extremely disappointed" over the incident. "Overall, I am extremely disappointed with my experience and simply cannot believe this blatant attempt to deceive me," she wrote. Hopefully many people will hear about this incident before their next car service and be more aware of this deliberate fraud. Hyundai has encouraged customers who feel they've been dealt an unfair bill to contact the company's customer care line, on 1800 186 306.
