SAA Voyager Customer Service Do Not Respond

<p>I have been trying to get my details updated since March 2016, I have emailed on SAA voyager customer service on numerous occasions as well as called the call centre who advised that they would escalate this to ensure the update happen, yet to no avail, still no changes made and still no reponse from customer service 5 months later. Unbelievable to be so unresponsive to your customers for what is supposed to be a loyalty program!</p>
