Discounts not honoured

Smart Shopper, for all its benefits, has not been honouring some discounts/vouchers due to me. If a voucher is loaded on the card, printed proof, not expired, etc, then the discounts should be honoured. Particularly these personalised vouchers, which successfully motivated me to buy something I wouldn't otherwise be buying. When I got to the till, the supposed discounts were nowhere to be seen. The staff at Douglasdale Pick n Pay are friendly but helpless, as Smart Shopper seems to be a different business or something, and the only resort they have is to phone the call centre.

I have a previous complaint of R50.00 due to me, and now this one, which is around R20.00. But there is just no follow up to honour these.

On 29 August I finally got a response, asking for more information, which I duly provided the same day. I haven't heard from them since. Needless to say, I'd like my R70.00 please, plus whatever sort of apology is reasonable these days.

(Remember the days of an overflowing gift basket when a company realised it had mistreated one of its valued customers!)
