Called and left a message: only picked up the last couple of words "will be fulfilled immediately." So I am guessing this was a lousy marketing call from an automated system that is not even well enough built to wait to leave a message!!!
Why would you even bother calling back? Expect most unknown numbers appearing on your ID to be dummies to disguise the callers' real numbers. Some calls may prove costly if you actually get through. 430 in the morning is during business hours in the Middle East. Do not answer in any way, block the call, or set your phone (if you can) so it doesn't ring for certain numbers.
