Having just spoken to support, I am very annoyed about the way this promotion was advertised. I received an email from paypal regarding this free month via paypal. These were the T&C's at the bottom:
* Xbox Game Pass “Bonus Month” offer cannot be combined with any other offer and is only available in Austria, Belgium, Denmark, France, Germany, Ireland, Italy, Netherlands, Norway,
Poland, Portugal, Spain, Sweden, Switzerland, United Kingdom to all consumers who purchase a single 1-month Xbox Game Pass from Xbox.com, Xbox console or Xbox app using PayPal as their purchase instrument and consumers who currently use PayPal for the their
recurring Xbox Game Pass membership payments (does not include purchases or payments made with any PayPal branded debit or credit card when used outside of the PayPal wallet). Limited to one bonus month per person. This offer ends on 31 October 2018 or while
supplies last, and is not redeemable for cash. Codes are valid until 29 January 2019. Please allow 2 weeks for delivery of your bonus 1-month code via the Xbox Message Centre. Microsoft reserves the right to cancel, change, or suspend this offer at any time
without notice. Xbox Game Pass subscription continues to be charged monthly at the then-current price (subject to change; plus applicable taxes) unless cancelled.
So this made me eligible for this offer. The email doesnt state further T&C's. As I subscribe via recurring billing I didnt go to the Game Pass website. I also wasnt directed there to read further T&C's. The next time I receive a promo from you, please make
sure the T&C's clearer than the above, expecially when they get amended 2 days before I receive the promotion and dont state this.
