Warning to fellow OzB's.
I tried to cancel my Coles Plus/Saver trials via three different browsers and whenever I click cancel, it says, "please tell us why you're cancelling" and there's no options or text box to enter/select anything,
Then I tried the online support and after asking for a human they "transferred" me from one bot to another bot, who couldn't cancel for me, then finally I called up and got them cancelled
I reckon it's deliberate to sign us all up with free trial then make it difficult to cancel!
I had the same issue.
Had to use a Chrome desktop browser in the end for the options to show up.
It's probably not malicious and just incompetent Web design, but it is a shitty experience. The whole Coles subscription and customer service is surprisingly garbage.
