BMO Harris Bank Account Or Service Complaint

BMO Harris Bank account or service department,

Checking account Account opening, closing, or management Indiana

I applied a checking account with BMO Harris on - with a promotion code. The promotion said that I can get $200.00 bonus if my account receives direct deposit over $300.00. I opened the account at a branch and also showed the promotion letter ( code included ) to the banker. Every month there are - direct deposits going to that checking account from my employer. But until today -/-/2016, I have n't received the bonus. I called BMO customer. The representative asked for the promotion code when I opened the account. Well I do n't have it since I threw it a few months ago. I do n't know what to do now..
