Every 3-6 months I get a phone call from a real estate saying we're on their list of people who had been enquiring for houses and wanting to know if we were still looking to buy in the area.
We bought our home from this real estate almost 4 years ago. I've told them so every time suggested they remove my name from this list as we're happy here

but 3-6 months later I get another phone call.
I'm also on another list with the same real estate which gets phone calls and letters asking I we'd like to sell the house. They started just over a month after we bought the house

bright buttons aren't they?
