Poor response from SAA Voyager

Very frustrating!

On 1/03/2018 I contacted SAA Voyager about information to use my Voyager miles before they expire. 19 days later - still no information. I received an email response dated 08/03/2018 to which I responded to on 09/03/2018. I have called the number provided - no progress there either.

Is the idea for my miles to expire first?
