second time ADT messing up my bank account

When I subscribed with ADT I told them to debit my account on the 20th of October to my surprised I was debited on the 1st of October which left my account overdrawn. Now this morning I wake up to being double debited I called to find out what is the money for I was told it's a renewal fee, fair enough but who did they notify I did not get an sms for this. And how do I pay a renewal fee when I've only subscribed with them in September. I need that fee reversed as I was not made aware of to adjust my account for the debit.
