I hate the bank!

So when we moved I ordered new checks from the bank. They get here finally after being delayed by a month! I write all our bills out and mail them not thinking anything. Get a call from the bank today informing me that they had to reject all my check cause the wrong account number was on the checks...That means my rent "bounced". So embarrassing....I had to call our landlord and explain to her the whole situation, luckily she laughed and told me to bring her the money by Monday and is nice enough to not charge us any fees and will still let us write rent checks. But now I have to deal with the 10 other people I wrote checks too!!!
