This bank is a thief

On 11/22 I opened (or thought I was opening) a checking account with this bank through their website. I gave them the deposit information, and got a confirmation email that everything was set up, including my $100.00 deposit. On 11/28 I received my check card in the mail. I activated it, then proceeded to go to the website and access my account information. THERE IS NO RECORD OF MY DEPOSIT, and nobody at the customer service # seems to be able to find it. I have filed with the BBB but I am furious, so I am letting everyone know I possibly can to avoid them like the plague. I really hope someone can help me with this, because the money has to be there somewhere. I'm not working right now so 100.00 might as well be 1,000,000. I am so upset, I am to the point of crying, and when it gets to that point, look out.
