Promotion

I received an sms stating the following \Shop the latest looks at MRP and get R100 off your spend of R500 on your mrpmoney store card. From 22-28 Mar. promo:\". I won't state the number here. It does not say T&C apply nothing. When Mr price in lifestyle center Centurion called head office they said the voucher is valid but when entered in the till it say invalid. After 40mins of standing by the till head office basically just said voucher is not valid. This is disgusting service as I spent over R500 and did not get my R100 off. Don't send out SMS about promotions if they not valid. I want my account to be credited with R100 as legally that's what the promotion is about!!!! "
