Auto Pay and Credit in Account
I am new to Cricket. I just joined (via ebay seller/T-Mobile port) yesterday.
I currently have $40 credit in my account.
If I sign up for autopay, will my credit be used by the system before billing the card? Or should I wait until all my credits are exhausted before signing up for auto pay?
I also have a referral code. Where can I apply it? A quick look into my online account did not show me where.
