Makro voucher query - NO FEEDBAC****!!!!!

If I could give a 0 rating I would.

A few months back, I used my rewards points to redeem a Makro voucher (which I did not immediately use). In November 2019 I received an SMS saying there is a problem with the voucher code and they will send me a new one (which they did and the SMS said it is valid until March 2020). When I decided to use the voucher in January, I could not redeem it. The error at the store said that the voucher was already redeemed.

Needless to say, I sent an email to Vitality on Monday 6 January 2020 to query this. Long story short and after many emails back and forth (mostly of me asking when I will get ANY feedback), they told me that the voucher was redeemed on 23 December 2019. I told them that I definitely did not redeem it and obviously they sent me an incorrect / duplicated code with the initial SMS. They told me that they will investigate and give me feedback within 2 working days (this was on 19 February 2019 - already more than a month later!!!!!!!!!!!). To date, I have not had any feedback. This is the longest 2 working days ever.........

Moral of the story, between 6 January and 3 March, my query is still not solved.
