Extremely bad service

I have a terrible experience with ADT. I currently do not have any contract with them. They are still taking money off my banking account. I had a 2 year contract in my daughters name 2***. When I app**** in my name, it was declined due to affordability. But the sales person Clinton John said he could change me to something else without any further explanation and did not ask me to sign for the new deal. This deal was for a 2 zone in a 5 bedroom house. I find that to be an insult.I currently have a 8 zone from my daughters contract. Without me knowing what deal it was, they took money off my account. When I enquired, nobody could explain. I have sent several emails to the head office since last year in September, still not resolved. Instead still taking money off my account, spoiling my account as sometimes there is no money in my account. Someone called me earlier this year and they sent a technician to look at my system, the technician decided to change the battery which I had no problem with. I sent an email again, with no response. I started to reverse the debit orders. I was called by Berand, I explained my issue he asked me send him all the emails which I did, that was in April 2019, no feedback yet despite follow up emails that I sent. Later in May M Cherry also called said would look into the matter, I am still waiting and they are still taking money that they cannot even explain what it s for. I do not know what to d anymore. On Wednesday 03/07/2019 they tried to take money off the account, it bounced as there was nothing. I transferred money on Thursday 04/07/2019 to use for something, they (ADT) debited my account again, and they took the money. This is like a game. Can someone please assist.
