I have been receiving calls from this number for the past year and a half to two years, ever since I replied once to the American Cancer Research Center and Foundation's mailing requesting donations, at their listed number of 888-567-0102
. Ever since then, I have been receiving calls from 813-881-1700 EVERY MONTH for about two weeks each month. I put them on call block, so they started calling using the number 11813-881-1700 and a couple of other numbers. Today I received another call and even though they are blocked, they are taking up space on my call block and I only have 20 numbers I can block, so I called them and told them to take me off their list, that I'm tired of them calling me two weeks out of every month, and that if I want to donate something, I will call THEM.
