Spar e-vouchers service is unredeemable.

We recently won a e-voucher through Albany to redeem at Spar stores listed on their website who accept e-vouchers as payment. We contacted at least 10 of those stores listed, who said they do not accept e-vouchers and most of them did not even know what e-vouchers are. We also visited a few stores on the list, which did also not know about e-vouchers. Spar should really inform their stores that they are listed as accepting e-vouchers. Or is Spar e-vouchers ******** consumers?
