It's a huge company with many departments. One problem is that for some departments we can only email them to get info for customers. we can't contact them directly and resolve the issue or begin to resolve the issue until they email us back which although usually is by the next day, but sometimes they don't email back and that customer wants you to call them back when you find out the answer. When you take 100 + calls / week you're not going to remember about that one call from way back when if that dept doesn't respond to your email.
