We get calls from this number 1-4 times a day. This has been going on all summer. This is from an air conditioner company in Pennsylvania. The company calls and we answer and repeatedly tell them we're no interested. This stops it for about a week. Then they continue to call and leave no messages. The email address is http://www.unitedairtemp.com/.
I get calls from this number several times a day for the past three months. No matter how many times I tell them I am not interested someone else calls from the same number trying to sell me something.
I get calls every day from this company. If you go to their website, they have their customer service number that you can call and get taken off their call list. I don't know if this will really stop the calls, but it's worth a try.
