No Calls for approximately 8 months - Need to Cancel

For the past 7-8 months, when our alarm goes off, no one phones us to find out if everything is fine. I was in contact with a lady at Chubb who said she couldn't see anything preventing Chubb from phoning us. She would have to talk to someone at the call centre or management. I received no reply from her. When I followed up 2 weeks later, she still did not reply. I have now tried to make contact with someone at Chubb on how many occassions and don't get any feedback. Made calls, sent e-mails, logged online queries - but no reply received. I seriously cannot go on with a company that does not care about my family and my safety. My debit order goes off each and every month, but I don't get any service! I have been in contact with another security firm who promised much better service. I just need someone to contact me to have my contract cancelled with Chubb. I want to make sure about the cancellation fee not having to be paid as per the Consumer Protection Act. This is really pathetic service.
