Three times this week. Now blocked.

I have been on the "do not call" list for years.  This is the 3rd call within the last couple weeks from this number (240-318-1569).  Indian guy selling air duct cleaning for "Home Services Maryland"

They called my unlisted number this morning.  No message left.  Caller ID said "Cleaning Service."  I wonder if anyone knows about a call blocker that not only blocks numbers, but particular Caller IDs -- full or partial strings.  That would save a lot of time and trouble.

Unwanted call. Left no message. We are on Do Not Call List.

They have been calling my home number for weeks.  Last week I finally picked up and spoke to the man and asked to be taken off the call list.  Today, July 31, I got another call, at 1 pm.  I asked again to be taken off the list and said I was going to report him if he continued. He said, "Anything else?"  I said to just take me off the list, to which he responded, "I just did."  I thanked him and hung up.  We'll see if his word means anything.  The number he was using was 240-318-1508, which came up as "MD Cleaning Service."
