A.P.I. Alarm review: Lack of any response for cancellation

Funny how emails to their billing department go unanswered for cancelations. Calls go on hold for 25mins+ when when you mention "cancellation" on the automated system. I've tried 3 emails, 5 calls. All no response.
Decided to try calling about installing a service, how quickly that gets answered, transferred and held once again indefinitely when you mention cancelation.
If this is the ethics to run your business, I for one, will not trust you for "security".
