what to do ??

This number has been harassing me as well with merciless repeated calling. They called five times this morning and many dozens of times clustered together in the past. I called my cell phone carrier to ask them for help in blocking their number, it's always the same after all, but they said because I have an iphone they cannot help me. I am so mad! It makes my phone impossible to use when they call back the second they hang up. Like an internet denial of service attack! Who does this kind of thing?

any one with the same problem with a fax from Toronto that faxes 15-20 times to your wireless or home phone?? let me know

Yes, this fax keeps dialing my phone line....grrrrrr
