Wowcher Wallet Credit? 14 January 2022 at 4:31PM in I wanna buy it or do it

Hi, after complaining to Wowcher they credited me with £8 to my wallet but there is no apply wallet credit box showing when I try to buy anything.  I've checked and the credit is in my wallet . All the deals I'm clicking on in the fine print say 'no marketing credit can be used' does this mean wallet credit is actually unusable?   Or am I doing something wrong?
