Edgars calling me and just putting phone down

Over the last month or 2 I have been getting calls from number *** as well as ***. I can hear there is somebody on the other side and then the person just puts the phone down. I see on Tellows that other people had the same experience with this number. Today after saying \hello,hello\" a guy on the other side said \"Sorry wrong number\" I insisted on some answers and he said they are only supposed to phone people who were born after 1960. I asked why am I getting all these calls and he just said he will take my number off the list and get his manager to call me. What is Edgars thinking. Needless to say that when I called the number it just says \"The number does not exist and that I should dial carefully\". Can somebody at Edgars please have a look at their system and train their staff and STOP PHONING ME AND PUTTING THE PHONE DOWN IN MY EAR."
