Terrible Service and Incorrect Invoicing

I had an alarm installed by Fedility a few months ago. There was numerous problems with false alarms and also an incorrect radio installed. I had difficulty in getting Fedility to rectify this with numerous phone calls and emails. During this time I started receiving incorrect invoices over charging me for the installation. I've send numerous emails and phoned the person who quoted me without any action to rectify this. This is still not sorted out. I would not recommend Fedility to any person!
