Avengers beta code

I bought a beta code for avengers game but the code is invalid I keep sending screenshots with no response I bought the code on Saturday kept trying code over and over at least 3 times daily and now beta has started and now I can’t play the damn game because you sent me a damn invalid code refund me my money or send the right damn code I mean honestly it’s unacceptable I’m missing out on something I paid for while your agent cant respond to my query I’ve never had any problems before so why the hell now honestly one of my most anticipated games and now I can’t enjoy it plus I lose out on my cash
