purchased too many tokens

Issue: I purchased 1500 tokens that didn’t transfer into the account until hours later so in the meantime, I thought something was wrong and used a different card. This time it told me there was an error so I tried once more, error again. I stopped and checked a few hours later and the tokens amounted to 4500, I’ve tried contacting developers on discord and have been ignored so needless to say, I’d much appreciate a refund please and thank you.
