I never get the FIFA Points ! :(

You need to contact EA. They should be able to provide you your missing points. Make sure to follow the specific instruction on this page:

How to report your lost or missing FIFA Points

Hello DbulHelix,

You can earn Xbox Live Rewards Credit in two ways:

1. By finishing the offers located on the MyMissions page at https://rewards.xbox.com/mymissions/ .

-or-

2. For non-offer purchases, you can earn Credits by earning a one star MyVIP level through purchasing at least $300 USD or regional equivalent of eligible content. After you receive your first star you will begin to earn a percentage of your eligible purchases
back as payback Rewards Credit. Pre-orders, in-game consumables, and subscriptions are not eligible for MyVIP.

In September 2014 we changed to the MyVIP policy. As a result, payback based off Gamerscore (MyAchievements) was discontinued. Also, as of July 2014, we do not award Credits for Xbox Live Gold renewals. In September 2015, we made some refinements to the
program. One change that happened was an adjustment of MyVIP purchase thresholds. If you did not reach any MyVIP ranks with your purchases from September 2014-August 31st 2015, you were placed at a default rank. Since you were a zero star member, you did not
get payback Credits on your purchases. You can check your current MyVIP level/progress at (https://rewards.xbox.com/myrewards/).

Since you just hit your first MyVIP star, you will begin to see payback for your purchases. Payback is calculated as a monthly sum, and placed as pending in your account midway through the following month.

Regarding your World of Tanks purchase, from the FAQ for that offer:

Which Xbox Store content is eligible for this offer?

This offer is only open to add-on content for Free to Play titles purchased from the Xbox Store. Add-on content includes but is not limited to gem/coin packages, additional skins, starter packs, etc. This does not include purchases made within the game,
as well as purchases made using premium or earned currency.

Since your purchase was made through an in-game storefront, and not the Xbox store, it was not eligible for that offer.

I bought 12,000 Fifa points yesterday at 7pm, money came out of my bank account never received the points and never received a confirmation email from Microsoft.

Yeah that's what I am starting to think. Simply because I have never played FIFA so I don't know if it's this FIFA hack or whatever it's called. But it's starting to point to EA in my opinion. So maybe I should change all of my EA account or get rid of it
altogether.

I just noticed that my account has been hacked. How do I report a Fifa hack to Microsoft? I heard there's a way for investigation.

=== EDIT ===

You can see the FIFA icon next to my avatar. I don't even have a console! I have never played FIFA and I have never used a console, but now I have FIFA achievements in my account and my ms points have vanished. :O
