Not true about a refund at all. I was 29/29/27 in game so many hours sunk into the game.
Want a refund? CALL microsoft store directly in your country zone( USA, CANADA, AUS, ect) with your order number (digital download) and all of your info, as in email, payment method, ect.
The people that I spoke to at Microsoft / Xbox store are WELL aware of the issues and complaints - in fact the rep actually took the time to skim the forums here and the official news reports from SoT.
Long story short, 3-5 business days and I have my money back. I honestly wish it hadn't come to this but my decisions alone are based on horrid pings ranging from 75-1100 at times, seeing everyone else in their pre ordered gear but not having access to it myself, the various 'beards' messages, and finally the inability to even play at times due to the servers being locked out.
So yes, it is possible to get a refund. I hope this info helps someone else thinking on a refund. Another way is to just call your financial institution and do a refund that way as well. Most people pay with credit card, and due to Microsoft using these companies as a payment window, they MUST follow the rules of that card company, which varies in different countries, but in NA, they must complete a refund within 3-5 business days, or be frowned upon by the said CC company for non compliance.
Good luck to those sticking this game out. It has serious potential, but not at this time for me.
