Hyundai are Clueless and Bad Service Providers

I am deeply annoyed with the service i received from this dealer i went to purchase an i20 when i test drove the car i was told the car was a 2014 model and cost of R129995.00 and it had plus minus 28000kms on the car. I then told the salesman to send me the OTP as i was going to take the car. When i received the OTP the car on there was a 2013 i20 with 83000kms for R135000 when i called the sales man he then rep**** saying the car i drove was the wrong car he showed me, when my mother went to the dealer had nothing to say, i cannot believe the salesman have nothing to say on this or have no experience or know the cars they selling absolutely pathetic service I'm actually glad i never bought a car through them they are useless. At first they are so helpful and bend over backwards for you then when you say ok let's do the deal they become like they have no clue what is going on. I would really like to received feedback on this matter. Sale Person Garth Thompson.
