I WOULD NEVER ADVISE ANYONE TO GO WITH THIS COMPANY!!! I've been with them for two years now. 1 year with go skippy before them (come back annoying go skippy hold tune, all is forgiven) they do not require a box so I never had any battery problems then. My battery was relatively new when I purchased the car, just before getting a quote from go skippy. I had the box for approximately a month and the battery died. I took the car to halfords who said there's nothing wrong with the battery. Since having the box my battery has died 4 times. Last time was 24/12/16. I called to report it they said I must get a mechanic to say the box is the problem. I keep trying to explain that even if I wanted to buy a new battery I couldn't have it installed as it would mean invalidating my insurance If I took the box off so either way they would be forced to come out regardless. But they refuse to come. So in essence they are holding my car to ransom. forcing me to pay more out of pocket expenses then I already have due to this problem. Either way they still have to come get the box off my car but they refuse. I dont know what to do. It's very frustrating.
