Blue Security

I signed up with Blue Security had the alarm system for about 5 years. I moved premises, alarm was transferred, paid for transfer and monthly premiums every single month. Alarm was not functional from July 2019. debit order still went through. Reported alarm not functional. I was told it was battery. That was not the case i did buy battery before my move paid in full. Technician was sent in to remove radio because i sent email to cancel alarm contract it was not working and technicians did not rectify. I also sent an email to the area consultant of Queensburgh. She copied me on all responses from accounts department. Debit orders are being taken order from my bank account which is *****. The accounts department is changing amounts and helping themselves with my money. I stopped the debit order from August 2019 because i don't have the alarm system. Why should i pay if i don't have the security. I have all the statements of monthly debits, Battery charges and the move from one premises to the other. I also have proof to say the call out fee for the faults was no charge. So why ***** from my account. Please help
