Query: Caller ID does not work

I bought this phone for my kitchen. I wanted a wall-mounted phone with caller id.The phone was easy to set up, after inserting 4 new batteries, I set all the options (contrast, date and time, area code, etc.). Everything worked correctly EXCEPT the caller id. Callers are not shown, even the number of calls received does not increase. Batteries were fine since I could see all the other data displayed (date, time, et.) on the screen.I thought it was just bad luck and returned the phone to the store in exchange for a 2nd one of the same kind.Same thing with the 2nd phone too...I am returning it to the store today and will definitely not buy from this brand again.BTW: I have caller id on other phones in the house so the problem is not from the service being installed or not.
