ADT DAYLIGHT *******ION AND ******* WITH *********** STAFF!

I called for the cancellation of service on a property I sold. I requested for a reference as the cancellation department was not answering calls on the day and the person that took my call sent an email to the cancellation team. Two weeks later I called AGAIN to follow up only to find that nothing had been done at all and only today was a cancellation form sent to me then suddenly I'm told that my notice is late which means ADT will be deducting money from my account on a delay that they themselves caused. The new property owner is also in a process of continuing with ADT and this will result in a double deduction of one property. THIS IS DAYLIGHT *******ION AND ******* WITH *********** STAFF!
