Spur a taste of embarrassment !!

My daughter purchased a gift voucher from Spur online as a fathers day gift to me because she was stuck in the UK during lockdown , the voucher was in Rands etc. When I attempted to redeem it or use it at Rocky peak spur , they said it was not valid , even when they telephoned the head office they said the same , No explanation or help offered in solving the issue just more or less told to forget it. Spur head office through emails eventually sorted it out. But why did I have to go through this ,surely it should have been sorted out in the store , why did head office or the store not ask for my details so that they could get back to me , really made me feel like I was begging for a meal , NOT GOOD !!!!
