I have not received 10 virtual keys for pre-ordering Forza 7

Hi Metalplex. We do not see a Forza 8 Pre-Order purchase on the Microsoft account associated with this Gamertag. Purchases had to be made from the Xbox Store to qualify.

Anybody from support can help me with this?

Hi! This is from the Faqs:

Rewards Credits for pre-ordering or ordering the game will appear as pending in your account within 96 hours of the offer end date.





Forza Motorsport 7 Virtual Key Instant Win & Sweepstake Faqs

Hi GDane. There was no offer that awarded for pre-ordering Forza 6. Credits for pre-ordering Forza 7 are only awarded if it was pre-ordered or purchased during the offer period. Since your pre-order was made in June, it does not qualify for the Credits.
We are looking into the keys for your pre-order. Hang tight for those.

Since you preordered before the offer began, your preorder is not eligible.

PRE-ORDER/ORDER THE GAME

Pre-order or order any digital version of Forza Motorsport 7 (includes Standard, Deluxe, and Ultimate Edition) from the Xbox Store between September 18 and October 13 to earn 10 additional keys and 5,000 Rewards Credits. Please note that it can take
up to 96 hours for your keys from this action to appear on the site. If they haven’t appeared by the end of the contest on October 13, you will have until October 20 to use them.

it does not say that on the webpage and there is this from the official rules "Pre-order or Purchase the digital format of Forza Motorsport 7 (Standard, Deluxe, or Ultimate Edition):

Pre-order: By October 2, 2017"
