Has anyone else found GrabOne has started sending out daily emails without consent starting on the 28/03/2019 for old accounts?

I have an old account that has been dormant and VERY unsubscribed for a long time.. suddenly they've started sending me daily emails.. I haven't purchased anything, nor in any way interacted with their service for quite some time. I have certainly not "resubscribed", that's for sure. But when I log in, Auckland daily mails is now "ticked".

Anyone else in the same boat?
