NATIONAL SECURITY & FIRE - PATHETIC CUSTOMER SERVICE

I was a customer of Apcan security for about 4 years, I was very happy, always great service. Unfortunately Apcan was acquired by National Security & fire, well all I can say is that customers do not come first and that National Security and Fire need to learn about customer service. I cancelled my account, all was in order, received confirmation that my account will be cancelled 30 June, I received an invoice today I owe for July, when i queried they said I owe for July, I have never been more ****ed off. NATIONAL SECURITY & FIRE, GET YOUR ACT TOGETHER
