I had a problem where one of my missions would not track properly and I didn't receive my rewards.
I contacted support and they told me unless I had screen shots that they were unable to verify if I had received the reward or not. Two days later they reply in the usual copy-paste unhelpful manner we have all come to expect from WG support.
They told me that unless I had taken a screenshot of the mission progress and the fact I didn't receive the container they couldn't help me. I don't even know how that's supposed to work. Take a screenshot of something I didn't receive in the first place? Ridiculous, other companies such as EA have the ability to verify whether an account has received their rewards (battlepacks in this case) properly. WG don't posses such tools.
I have had this problem happen in the past with missions not tracking properly and restarting the game has always fixed it. However this time it did not fix the problem. So the thought of 'screenshotting' my progress really didn't cross my mind and in my opinion nor should it.
If I had known this problem would occur then I would have taken screenshots but that's a very unrealistic expectation for players to screenshot every mission over years of play in the unlikely situation that a problem would arise.
So if you don't screenshot all your mission progress then WG support are unwilling to help.
WG customer support has one of the worst reputations in the gaming industry and this was probably the 4th or 5th time since 2012 that they wouldn't help me.
As such I've decided never to play this game or any other WG product ever again. I can't risk something going wrong with my account or bank details and they are powerless/unwilling to help.
I'll post the full conversation here and on reddit (although I can assure you my reddit post will be less pleasant). After all the years of financial support I'd expect a little bit more than a copy-paste reply.
