Strangest Rejection!

Last Monday, I made the decision to withdraw a submission from Carina Press. I sent them an email (to two different places to make sure they got it). Today I got a form rejection letter. Strange! Obviously they didn't get my withdrawal or ignored it which from their website they seem so friendly. What a slap in my face! Not that they need my manuscript. I'm sure they'll do wonderful. They have an awesome website and to be honest I learned a great deal about the power of the computer from them and intend to use it to my advantage. So all isn't for naught, but does humble one's self when first you get ignored and second getting a form rejection letter!
