Unhappy Customer with Security Company

I am very disappointed with ADT.

I cancelled my contract with them and gave them a months notice. First I called and spoke to Agent A and she put me through to speak to Agent B. Agent B said she will speak to Area Manager to contact me. After waiting a week they did not and I called Agent B and said please cancelled it and she told me only then to put it in writing. Why did they not tell me the first time I spoke to them. Secondly they say I owe them because I was paying one month in arrears, but that is correct because I paid the same month I signed up with them. I also paid for the extra stuff they put in. The more I tell the credit control person to look at my records they keep telling me that we all pay in arrears and I must pay up.

This is the same people when they broke into my house phoned me that everything is in order when my alarm went off, in the mean time they robbing me and security company says everything is in order.

Please people, make sure that when you sign up with a company that you are informed that you are paying in arrears and.
