very unfriendly service

<p>Back in 2014, my car had a mechanical problem while at Bloemfontein. I sent it in for a diagnosis and repairs at nissan in that place.</p> <p>They promised to contact me about their findings which they didn'. I returned home in kzn without it and no one bothered to call me. I went back to find out only to be handed car keys and told 'no problem.'</p> <p> </p> <p>What annoys me most now is that whenever they have car specials they send me smses. I sent them emails to be removed and also chose 'opt out' because I wanted nothing to do with them, but to this day I still get these messages. Even if I go work there again I won't go to them.</p> <p> </p> <p>Can the head office remove me from getting any type of communication from this branch?</p>
