Debit orders dispute

National Security and fire is the worst service provider I ever sign-up for. I have the alarm for 5 months and is extremely unhappy how they can deducted money out of my account with out my consent. The agreement was that I will pay them R375 every month. But last month they deducted R1170 from my account. They don't care about you as a customer. Extremely unhappy and will like to cancel. I will advice no one to join up with national security and fire
