So far this year we (our association) has received 4 calls from Dennis Riordon with John Thomas (caller ID 212-299-7820.) I did some research and found this exact guy and called him back 800-257-1537
x7820 and informed him that are requesting to be put on their do not call list. Everytime he calls, we request it but he hangs up before we can confirm that he has done so. This time I got his attention and he confirmed that he will not call again. I have our attorney general on stand-by should he call again!!!
