In the UK we have the Consumer Rights Act 2015, with purchases related digital content legislation, companies must provide what was advertised or promised when a customer makes a purchase. If there is a failure to supply digital goods, rewards, or compensation as explicitly promised, this may constitute a breach of contract or unfair trading. This includes bonus digital items (Battle Passes, XP tokens) that were publicly promised as redress for outages or purchase bugs affecting UK customers.
In the original public apology it mentions those affected by the EA App glitch would get the battlepass as compensation, they cannot publicly make a promise then renege on it because it doesn't suit them, it actually a criminal offence...
Do you have an idea how to report this in the UK/EU? I know Canada and USA has the BBB (Better Business Bureau) which, from my knowledge, some people used and actually won the case, since it goes directly to EA and not just stops at their support.
