Called my wife's cell while she was napping. I answered with a heavy Mexican accent and pretended not to know English. I think it may have been a recording that was programmed with certain responses depending on what the contact said. The first two times it didn't understand me, the voice started from the beginning of the dialog again. The next two times, the voice said "Hello, are you there". I hung up after that.
The company calls me every day. It's becoming more and more frequent, and is really starting to annoy me. I answered once, and it was some cruise line offering me free tickets. When they asked for my credit card number, I hung up, but they still keep calling.
