We got a call from this number today at 6:03 pm and didn't answer. The caller ID was WALTHAM MA. No voicemail message was left. Thanks to all who posted information. The number will be added to our call blocker. I highly recommend such a device to avoid these nuisances.
Hey folks, what would happen if we all started toying with these people, tell them to hold on while you turn down the stove, telling them to wait because you just got out of the shower. Then make them wait and wait.
How about if you tell them to hold on because you are close to [***]. Then making noises.
Wow. Your idea is so fresh! Or it was in about 1964....
If you are getting this many calls, you are already on a "black list". The reason you get all these calls is the scammers know you are answering calls from unknown numbers and I bet you return calls you miss. I am guessing you like the attention, since you are doing things that will get you more and more calls.
There is no scammer black list. Your great plan is not even up to beer party standards. IF you want fewer calls, start blocking and don't answer or return the calls. Otherwise, carry on!
