SCAM warning

A guy with a foreign accent pretending to be from the UPS delivery service called this morning. He must have been new at this because he kept repeating the opening line. I got the feeling he was reading from a script and didn't understand what he was supposed to do next if I didn't respond with the correct phrase. It was an 876 number. I have a mailbox at the UPS store so I know this wasn't a legit call. I told him this was a scam and he hung up before I could get further. Which is good because he after he gets his act together he or the powers that be might change their tactics.
