Calls for a Stephanie have continued for 2 1/2 years since I changed my number due to the same problem. I'm on Do Not Call and have Call Block from Verizon but, as noted above, they merely call the next day from another number.
Frequency has increased since Sept 2010, often at 8:30 in the morning, even on Sundays.
This numbers calls me a dozen times a day and has done so for the past three weeks. They never leave a message. When I blocked that number they started calling from another one. Same thing again, a dozen calls a day. I'm on the do-not-call-list, I pay my bills, never declared bankrupcy, never took out any payday loans. I here some of these numbers are a scam looking to bully people out of money they really don't owe.
