Login to to your self serve account using secret/incognito mode and check your account balance. Do you see a credit of $10? Is your plan and add-ons page now showing the $15 plan?
There is a reverse autopay glitch now that will charge your payment card the old plan amount despite changing to the new plan and it credits your account balance with the difference. Don't worry it won't happen again it's just a brand new glitch with our brand new self-serve accounts.
If you don't have a $10 balance and your plan change to the $15 plan or it just didn't change at all contact customer support to correct this and change your plan to the $15 plan and credit your account $10.
You can use the links to contact customer support supplied earlier in this thread or scroll down to the bottom of the page and click on SIMon in the green section to submit a support ticket to customer support.
