Lost customer forever

After being a loyal and supportive customer at Truworths for 20 years, spending an inordinate amount of money with this group over this time, I was extremely frustrated when trying to make a purchase on my account on Sunday at truworths midlands mall. I keep all store cards in an app so as to avoid carrying them with me. On trying to conclude a purchase for my wife’s birthday I was told that this presentation of account is an invalid method and my purchase could not be made!!! Seriously Truworths, are you so far out of touch with app technology that a long standing customer is refused his purchase? Seeing as I walked out the store empty handed - sorry for you Truworths, I will be closing my account and will never shop in your stores again!! Not Truworths, not Earth Addict, not ****** Mary - no more customer.
