ADT COMPLAINT

We cancelled ADT on 27 May 2019 in writting. Begining of June and beginning of July deductions were still made from my account, 2 months after cancellation. Again we phoned because nobody came to fetch the transmitter after 2 months, again no return call as promised. We again complained in writting. A technician came the following day and removed the transmitter. That evening some of the money was deposited back. On 1 August R701. 86 was deducted AGAIN. How ADT do I get my money back and stop you guys from taking it again next month? Why must I take off work to go to my bank to try and resolve it? I was warned that this is happening to alot of your clients, I was also warned that this will continue. I'm horrified by this. I will never again join you guys. You messed up my whole budget. I will not ever recommend you guys to any one. How do we get our money back. Cancelled in May but still taking money in August. Bad bad services.
