Have been getting nearly daily calls from 718-219-3668 and now also from caller ID Guglielmo Lino with the same number listed on my phone. We do not answer calls that we do not recognize and I will look each up to see if this is a piece of garbage or something legit that did not leave a message (very seldom). This number has never gotten any reason to be answered.
So as other have said... Good luck stopping this calling number
Or....if you don't have a whistle, just press the "1" and when they answer hold any key on the phone as long as you can. Trust me, with that sound they will also hang up.
A few months ago I got one of these types of calls. I pressed "1" and talked to the agent. I was very nice and pretended to be interested. I gave him the info he requested (all made up numbers BTW) and after 2 to 3 minutes I informed him that I don't have any credit cards and that I was just wasting his time. WHOA, he blew up. What followed was about 4 to 5 more minutes of him calling me every name he could and me just laughing and telling him (all this time I was very polite) he was wasting even more time. I thought he was going to have a brain aneurism. He threatened me and promised he would call me every hour from then on. I'm still waiting on those calls. If you don't have thick skin and foul language offends you, then this method is not for you, however if you can absorb verbal abuse (I'm an old sailor), then this method works great, plus you get the satisfaction of getting in their head and wasting their time.
I got a call from the same number about consolidating all my credit cards into one for 1% interest. I went ahead and waited for a real person ot talk to and when they answered, I asked them how they would know if I even had credit cards. Whether I have one or not should be private information. They just hung up on me. That suggests something not kosher. I think you and Iare from Wisconsin. I suggest we see if these calls come again and if they do we should report the number to the state attorney general to investigate and hopefully stop their crap.
