they ignore the do not call list

Called just now stating they were calling about our Bqck taxes debt. Since, we have no taxes owed and IRS doesn't contact individuals by phone, I've blocked this number!

They call every 20-30 min until I block them. They just hang up when the answering machine comes on. They also have @ least 4 diff #'s because they have been blocked 3 times by me, but the Caller ID shows "Polling Quest".....I just blocked them again.

I want them to leave me alone
