got a call today.  Been getting calls repeatedly from them from all sorts of numbers.  I heard this guys name is Rupen Balaram Sivaram and is a Tamil Refugee that lives in Scarbourough Ontario.   Also told he was a paralegal that had his license revoked, wonder why.  Says his company is Home Care Experts Air Duct Cleaners.  The guy knows we are on a DNC list but still calls.  He threatened me that he would keep calling one time when I blew up on him and said WHAT CAN YOU DO?  He is a total jerk.  Reported him to DNC registry again.  Hoping something gets done soon with him.

They called my unlisted number so I assume they dialed sequentially which is ILLEGAL so DON'T TRUST THEM.

I've told them to stop calling, they responded by telling me "no". Then the guy starts swearing at me.

Got the call also while we were out at 4:05pm  
Never stop calling!

Had similar call today 2:20 (Eastern Daylight Time)PM. agent says they have 50%off cleaning price , asks how big is my house? I reply 5 thousand square feet. He comments that it is a big house. He asks how many bedrooms it has. I reply two. , but it has multiple levels. He asks how many furnaces it has? ,I reply "you mean energy conversion devices", he laughs, but confirms yes, how many? I reply Two, Now here is the kicker, I tell him I have hot water heating (Its the most efficient, but no Ducts), so the Ducks are out back and they just got rained on today,so they are nice and clean. He finally clues in, and then politely says good bye.

Got a call at my home in Brantford from (905) 267-1263.  Silence on the other end, apparently no-one there.Attempts to call this number gets a recording saying that the "number is out of service".
