Pathetic service from ADT security (Cyril)

I have an ongoing query with ADT security, firstly they debited a yearly premium from my account without my consent, thereafter i started doing my payments through a transfer. To my surprise, they said my account was in arrears, i forwarded all my POPs. Even to date my account payments are not updated and this issue has been ongoing for 4 months now. Im being called by their collections department 4 times a day and they have also adversely affected my credit profile because the arrears are reflecting on my profile. I spoke to Cyril from the accounts department, he has been giving me false promises and is now avoiding my calls. ADT fix this mess and cancel that contract, i will look for another security company that values its clients. Your service including that of your finance department is pathetic.
