Cancellation of Account

I have had technical issues with the chubb signal and after multiple attempts to fix by their technical department I decided to switch security firms. I cancelled my contract based on non-service. It took 9 emails, 4 weeks and multiple phone calls to get an email confirming cancellation of the contract on 12 September 2015.<br> <br> I have now received an sms to state that I will be billed an annual communication fee on 1 October 2015.<br> <br> All communication in this matter has been at my instigation. Often I cannot get hold of the relevant parties and am told they will phone back. They never do. Emails go un-answered.<br> <br> This is a completely unacceptable level of service. I want an official confirmation of cancellation of contract and that no further monies will be expected or deducted.<br> <br> ta<br> Claire
