About 2 weeks ago I had a young man named Brandon at my door and he said he was with NCA. He asked my first name and number and then asked about air quality in the area and water quality and handed me a card with a stamped number on it and said i was entered in a contest to win $500 in groceries. Today i get a phone call from a girl who said that she was calling from NCA and that i was entered into the contest and the draw is feb 1 she then said but we did our early bird draw and you won. She told me my address i confirmed  and then she said they dont share my info then wanted to know if i rent or own my home and if im working unemployed or a student. I answered that I rent and am currently not working as the employer went out of province she then said congratulations and thank you and hung up. So we will see if my "prize" shows up . Its actually great as i have thier employee on video surveillance and the complex i live in has giant metal signs that state no soliciting of any kind.

Another update:
No one of course show up today even though they promised someone will be at my place between 5 and 6. No one either called. So I called Niagara Clean Air in St Catharines, (905) 688-6488 and was told by some man that they don't know why no one came today. He wasn't polite neither pleasant to talk to. Insisted that if I wish to get price I have to let them in to show me product. No one mentioned product presentation when they did survey.
Under call type I put prank call since their behavior is not short of prank call.
So seem that Niagara Clean Air is very foggy business.

Update:

Did called NCA company that is located in St Catharines and they confirmed that they do give prizes out for survey. Also gentleman that I talked to said that person who should come tonight had car broken down and they will like to come back tomorrow.
So will see.......

I'm just waiting for someone to give me call and maybe show up at my door between 7 and 8 pm. I too did win some prize and they are in area to deliver it so will see if that is true or it is some scam.

I just got a call from a woman with this number as well. She knew my name and asked my husband's as well. She asked if I worked and if my husband had a job. She said that a college student would be calling in an hour to drop off an early draw prize. They called me back about 20 minutes later and I advised that the number has been reported to the police and they said that NCA has to do with water purifier in Welland and that they have been in business for 15 years. I read some of the blog to her and she said it\s not true and that\s not what I reading. I advised I was looking at it right now, I read some comments to her, she said she will give my prize to someone else if that's what I wish. I said yes that's what I would like and she hung up..Not really sure what they are up to after reading this.

Woman called said I won an early bird prize and asked if I was going to be home between 5 and 6 pm. She knew my husband's name and said there was a prize for him too, only if he was home. I told her he wasn't  and then she said she would call back. She never called back.

On Friday June 29, 2012, I received a home call from the NCA (which I realized stands for Niagara Clean Air) phone number 905-688-3151. The female person on the phone told me that I have been selected for a $200 gift since apparently I had answered to a survey some time ago (well, as my husband actually did complete a survey over the phone a couple of days before it didn?t look suspicious to me at all). All I had to do was to be home that afternoon and spell me and my husband names and occupations over the phone. I actually did it with no hesitation. After all, the caller already knew my family name and address (now, I guess, from the phone book). I understood that I do not have to buy anything. Then I waited to be called back to get the name of the person who will come to my door to deliver the cheque. She did mention that a delivery person was in my neighbourhood at the moment. Nobody showed up at my door and I was relieved. I don't know if the caller really intended to send somebody over and sell me something and our occupations made her stop or she just needed our full names and address. Now, thinking a little more, I am concern about identity theft and I will report this incident to the local police station.

I got a call from this number today, and she told the same storry as above. She knew our address and my housband's name but did not know my name. She asked my name in order to put that on the $200 gift card, and I gave it to her. She said that their delivery person is in nearby area and will deliver the $200 gift card shortly, and someone else is calling shortly to coordinate the delivery. I got a second call in about 2 minutes after this from the same NCA company but different number (905-688-8922) and another lady asked if my housband is at home to receive the delivery. I said yes and she just haung up. Now as I searched for this number on the web I understood that this is all a hoax, but I do not know what they are up to.

This number called and woke me up and told me a won from their survey I mean I do do surveys so I was like oh uh huh ... And they told me I won a 200$ gift basket and told me all I have to do was to look at this air purifier and say how "cool" it is probably saying I must buy it or something and asked me who I live with and what do we do and if I had a credit card do obviously wants me to buy this air thingy.. So I think it is a hoax I guess like obvsiosly not getting a free gift....
