How do i report false advertising on your site

ust like previous patrons of this dealership i experience
Blatant false advertisement  and bait and switch .  On line
they advertised a used  KIA optima 2013 ex  leather  
sunroof and moon roof and navigation , for 21k i contacted
the dealer right away and set up to purchase all thru email
sent all my information had papers drawn up and drove 2
hours from L.A to Escondido after i got out of work to pay
for the car (everything was drawn up i was just driving to
give them my money) they had the car pulled up front . they
open the car for me and it is not the car that was advertise.
Vin numbers were the same  the stock number was the
same but this was an lx which is the base model but was
advertised as ex which is top of the line. I have pictures of
all this information even the deal that they tried to make me
which was 8thousand dollars more . everyone was better
apologetic admitted that they had posted the wrong
description on the web site. I have reported them to the
better business bureau and recommend you do the same if
you have a similar experience  www.sandiego.bbb.org  it
only takes few moments . yelp is here for us to help each
other but the better business bureau is here to hold them
accountable for they lack of ethics and indiscretion. i will
gladly send pictures, emails and txts i have  of all the
information i have to anyone who request  it . I am not
exaggerating about my experience .Oh and FYI the KIA
dealership across the street belongs to the same owner ....i
would expect the same kind of business practice  due to the
fact that the sales man got the car from that lot . Thank you
for taking the time to read this
