Poor after sales service from Mazda SA

<p>I recently purchased a mazda 3 from eagle ford and mazda and asked for a nav chip which they told me would be an extra 7000 rand . I told them that I had looked on the internet and the same system was only 1000 rand in the USA . However when I asked headoffice they told me that the price was due to the mark up in the dealership and not from head office . Which I found out is not true . Firstly it should come as standard with the car and at the very least should be a similar price as other countries </p> <p>MAZDA HEAD OFFICE</p>
