Haven't recieved my cashed in rewards to my MS account.

Hello ANT ANT ANT,

From the transition FAQ:

What about my current Xbox Live Rewards Credits and MyVIP Gems balance?

If you have any pending Rewards Credits in your Xbox Live Rewards account on May 31, 2018, or if you are expecting your MyVIP deposit for purchases made in May 2018, Xbox Live Rewards will convert them into your local currency and deposit them in your Microsoft
account by the end of June 2018. You will then have 1 year to spend that currency on digital items from the Microsoft Store.

This also applies to any pending Credits when you opted out of the program.

Xbox support does not handle the Rewards program.

Hello,

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.

Furthermore, Xbox Live Rewards Credits and MS Reward points are not the same currency.

96 hours is how long it takes for them to be added as pending on the Rewards site. They would be scheduled to deposit into your Microsoft account balance around June 15.
