Cancelled my booking 1 wk before Christmas!!! I'd had the booking for a month previous.
Left a voicemail saying that their technician was unavailable 24hrs prior to the appointment (if I'd have given such short notice then there would have been financial ramifications!)
They had no alternative. I now have no service as it's a nightmare finding anyone available this close to Christmas - which is why I booked so early in advance.
On the phone I told them that they left me no option but to leave an honest review - no response.
Terrible, unreliable service - don't leave yourselves frustrated - find another operator.

Approximate cost: $380
