I keep getting more of the calls I mentioned earlier, often 5 or more a day, from many different numbers, but almost all with the same area code, prefix and even the first number in the last 4 digits the same. When I have a few minutes I have started to answer them, put them on speaker and then start belching and making other rude noises. If they ask to speak to Sandra I ask them if they are Sandra.
I wish I had the time to waste I'd start calling each one of the numbers and playing games with the people that answer.
Your wrong numbers remind me of our office, our company name was one digit off from a well know media company, people kept calling us to complain they never got the paper, cancel it, change subscription etc. Even when people explained and gave them the proper number to call some were still upset with us, because they don't know how to dial the right number.
