1st time I called aerial force I booked in for a certain day and time. They then called me 4 times to reschedule it for a day early because there was an engineer local which I couldn't do as i wasn't there. They then called me an hour before I booked the appointment for and I wouldn't of been there until that time, they then told me they couldn't do it at the time we agreed in the first place. So I had to cancel it. I then called up a few weeks later. Booked it in and had a very nice chap come round (jake) and got it sorted stress free. 5 star for when it got fitted but because of the pain before I can't give it that
