Call centre, just going hello?

i get calls several times, they dont leave message, no one on the other end when answer

I get the calls more than thrice a day . Let me say 6 times a day including early mornings. I hate when one leaves no message .it bugs me. At least have thecourtesy of saying who you are and why you are calling. If you are a ghost let us know .Hahahaha. just humour
