It only really turned into an issue because i was too lazy to chase the bank up about my transactions being blocked but thought i would publicly post my laziness online.
So i bought a Woolies gift card through cashrewards for the first time in January for the 5% discount. All was fine. worked out great. then i tried again a month later and i was getting something like "error, try again" so i stopped and tried again later. Eventually messaged woolworths and they said my bank has blocked the transaction. Fair enough, couldn't be bothered calling up the bank and unblocking it so i let it be. Now, its in April and all my payments have been blocked, my internet, mobile, gym, insurance etc. etc. :D
Had to finally call up and talk to VISA fraud as they thought my card had been stolen as gift cards are apparently an easy form of theft that people can then sell on sites like gumtree for actual money
edit: was gonna move post to shopping category but it doesn't seem to let me move it once i've posted
Which bank?
