Annoying phone calls disguised as courtesy calls ring almost always at the wrong time of the day/evening.
How many such calls do you receive per week, on average? Do you take the calls or ignore? Do you hang up once you realize it's one of those calls where they are trying to sell you something or asking you to participate in a survey... for the 100th time?
It is interesting on your use of word "courtesy", after all that is the term the caller uses but the experience of the person who answers is totally different. It is an uninvited interruption to your home life.I am also on the "Do not call register" however I still get some unwanted calls. I thank them politely but am firm in my no thank you. I appreciate they are trying to earn a living so I treat them with respect but I ask them not to call again. We don't have a lot, but we still get those annoying Windows Scam calls, and I have to admit I am not as polite with those, as they are trying to defraud people and that is morally wrong.
I wouldn't call them courtesy calls. I don't get sales calls since I put my number on the Do Not Call Register. Now I only get charity calls, which are exempt, scams (those "Windows Maitenence" scam calls, it's already illegal so they don't care that it's illegal to call people on the register) and surveys. I don't mind doing surveys if I have time. I used to do phone surveys as a job and I understand what it's like. If you don't want to do it you just refuse politely and they won't call you again. They have a code of conduct that says they can't.
About 4 a day, so about 28 to 30 calls per week. I am just so annoyed. Now I have started getting calls on my mobile as well. I keep adding the numbers to spam. As for landline, I have stopped answering the calls. They don't stop!! They don't even ask if it is a good time to "chat". Go away annoying phone calls.
