Hi ​@Mike P your plan is not eligible for the auto-pay discount, you’d need an eligible plan for it to apply. Here is more information on the discount https://www.koodomobile.com/en/help/auto-pay-discount

When I logged into my account at the time, during Black Friday week, it was clearly advertised to me.   There didn’t appear to be any caveats to signing up. 

Your link is not helpful after the fact. 

I will be removing auto-pay effective immediately.
