Play Gun Lake Casino MI - Player's promotional code is not working.

So I received an email stating that there was a 10% deposit bonus match on any deposit made daily after entering the promotional code. I entered the code on the deposit page when making the deposit and it did not award me the 10%. It said invalid code. I tried later that day again and it's at the same thing. I contact a customer service and they said that I wasn't supposed to put in the promotional code on the deposit page but on the promotional page. Nowhere in their email does it state that and why would you have a promotional code box on your deposit page if you are supposed to put it in somewhere else? Very misleading and the customer service rep would not add the bonus which was only $4. Considering what I've spent with them I think that this is ridiculous and very sad. I also opted in when the message popped up after logging in today it was explaining the promotion.

Dear spencercbila,

Thank you very much for submitting your complaint. I’m sorry to hear about your problem. Please allow me to ask you a few questions, so I can understand the whole situation completely. Did you make the deposit even if the promotional code was invalid?

Could you please forward all the relevant communication between you and the casino to kristina.s@casino.guru? Alternatively, you can post it here.

Thank you very much in advance for your reply.

Best regards,

Kristina
