I got a message from them saying that they were trying to deliver a package to my address and no one was home. They knew my address, which is creepy because they did not seem like a legitimate company. The guy said that he wanted to know when he could deliver it. They left a notice on my door saying that they were California Express Delivery and left another phone number with an extension. When you call that other number, you are told to leave a message, but there is no extension. When you look up their company online, it is a very cheap looking website and none of the links work. I don't think it is a legitimate company and it is scaring me a little that they are knocking on my door. I am thinking about calling the police.
