Bad costumer service

Have been with ADT for 3 years now, not so bad, but when it comes to the communication between their departments then it’s a mess, one saying this and the other saying that. Try to speak to a manager, keep you on hold and then the line cuts off. Wanted to sort out my account, now they just send the account and I must pay up. This after I made 7 phone calls to ADT, spoke again to the different departments, same story, one is contradicting the other. So, the easy way out is for the client to pay the mess. This is NOT customer service at all. Still waiting for a manager to phone me. Hopefully someone somewhere will take customer service seriously and get this sorted out.
