Horrible support and aftersales service

Extremely efficient sales department, but horrific support and aftersales service. When I asked for a quote online they were very fast to sell me a package and get my bank to authorise the debit order, and that's where it stopped. Was booked and scheduled for the installation, took the whole day off from work but nothing, not a word. Phoned then the next morning, they had now excuse and very arrogant but eventually booked and scheduled an install for that same day. Well 5 o'clock that evening I've cancelled my subscription, very disappointed and they were too happy to cancel, no remorse or anything. I know I'm a small fish in a big pond, but luckily there's other tracking companies...
