Account not updated

I've been struggling with ADT security for a month now to update my account correctly. I've provided proof of payments and contacted them numerously to assist and solve my problem. They phone me and tell me they will send me an email address to forward proof of payment for the third time. This is really frustrating. My alarm was activated during the week, and I'm still waiting for ADT to phone me to ask if everything is in order or if they should respond. I do not feel safe at all having them as a security company. I send emails to report bad service, no one is answering or getting back to me.
