The Washington State Attorney General issues warning about CenCon:

I too have been scammed by them. They get you by advertising low alarm monitoring rates, but in reality, they are super expensive, charging you left and right for anything and everything that is expected to be included already. I'm paying about $50 per month. When trying to remove one item, they threw on a $35 charge to remove one item. Why do they have many good reviews. They pay their customers 3 months of free alarm monitoring if you write a good review on them. You don't need to pay your customers to write a good review if you are truly good. Stay away from them. Don't let them make it sound like these posts are false. Is the Washington State Attorney General's Office false?
