Booked a service which was not carried out to anywhere near an acceptable standard. Fantastic Services accepted that the service was sub par and stated they would take no money. $440 was then deducted from our account which Fantastic Services say was a 'technical error' but now refuse to refund the money. Their money back guarantee is a lie and whilst some of their cleaning crews may be great, unfortunately ours was not and their head office are completely unhelpful. We are still waiting for our money, which they had no authority to take.
