Hi Lynn, I also have started to receive calls at home from this number and my service provider is Comcast. After receiving this call and then hanging up, I punch the keys *60 on my telephone key pad whereas it prompts me to press the number 2 on my telephone keypad. After pressing the number 2 on my telephone keypad it prompts me to enter the number ( I then enter the annoying phone no., including the area code and the rest of the number). It then tell me that this will be added to my list of blocked phone numbers. I then press 9 on my telephone keypad to exit this. Note: you can only add up to 12 numbers free
