Do any of you guys still use the totum card at the Co-Op

Hi I've been using my card at the CO-OP for quite a while now to get the 10% but about a month ago it just stopped working with no message why.
I ordered a new card but it's still the same, just wondering if it's still working for anyone else.
Didn't really want to message totum with bring a Hukd student 😁.
cheers
