Does the new card's billing info match your account info? Meaning the name is spelt the same, address is the same, etc? 

yes, it does, card Is unlocked, and should be able to make purchases, but I want to change the info and it’s not letting me

Try using a different browser or try clearing the browser's cache to see if it resolves the issue. 

you have a point with that, I should also turn off ad blocking

still doesn’t work, can you get a Koodo rep to fix it for me?

Sure let me flag a rep for you 

Great, can you tell them that the Stream Plus account is for phone number ending 5790 and credit card ending in 0728?

Hi @moms 

Our apologies for the late reply here!

Are you still having issues with updating the credit card for your Stream+ subscription? 

We can see that you managed to update the credit card for the other Koodo subscription.
