ADT corrupt?

Their parent company is Tyco...hello!!!!!! I worked for them for almost a year as a customer service specialist in a local office...all the sales managers, sales reps and installers are horribly corrupt (well not all just about 10% of an office of 100 were ok) they falsify contracts, they close out jobs prebilling customers in order to hit their month end quotas (managers make bonuses) therefore your system is not installed yet but you are billed some times multiple times. They make it out like a once in a while fluke when it happens to them but it happens to many customers....it really is purposely done to hit quotas and then fixed after and then done the next month and so on so it just rotates...isn't that unfair to stockholders to have a false financial forecast given???? I did not buy company stock although I could have....new federal guidelines do not seem to work since most offices audit themselves...I for one will choose brinks for my alarm...anyone have good or bad experiences?
