Was hoping to have my rewards credits deposited early

Unfortunately there is no way to have credits deposited before the scheduled deposit dates.

For help with the Rewards program, you would need to post here -

Rewards credits are deposited by the following 15th or 30th of the month after you have at least 5,000 credits pending, unless you request an early deposit. Early deposits will be deposited on the deposit date listed on the site at the time that you request
the deposit. You have to have at least 1,000 credits pending in order to request an early deposit.

Have you gone to the Xbox live rewards section on Xbox.com and requested an early deposit??

Normal rewards deposits are by the 15th or end of each month if you have 5,000 credits and over

Also, it's not possible to have credits deposited any earlier than what is scheduled. Early deposit requests are only to have credits deposited before needing to have 5,000 pending, not to have them deposited before the deposit date.

Hello LordToddHoward,

From the FAQ on Vault Credits:

I claimed Rewards Credits from the vault. When will I receive them?

If you claim Rewards Credits from the MyVIP Vault, they should appear as pending in your account within 96 hours. Once they are pending in your account, the normal deposit process kicks in. Generally if you have over 5,000 Rewards Credits pending in your
account in the first half of any given month, that amount will be converted to your local currency and deposited into your Microsoft account on or around the 30th of that same month. If the Credits show as pending in the second half of the month, that amount
will be deposited into your Microsoft account on or around the 15th of the next month.

Please note you need at least 5,000 Rewards Credits pending to automatically trigger a deposit, though you can request a deposit for the next scheduled date as long as you have 1,000 Credits pending. Also, if you have ongoing issues with us depositing
into your account, such as your account not matching up with your billing location, you might want to consider choosing a different prize from the vault, as we won’t be able to deliver your Rewards Credits until the deposit issue is resolved.

Therefore, since you triggered your automatically scheduled deposit with Credits that were placed as pending in early March, those Credits will be a part of the end of month deposit cycle. It is not possible to get a deposit outside of the mid and end of
month deposit cycles. "Early deposit" refers to the ability to request a deposit at a Credit amount before reaching the 5000 Credit amount that triggers a automatically scheduled deposit.
