Misleading advert and unkept appointment

Last week I called Margaret concerning a house advertised by property 24 I received an email that the house was available and it was a new advert ,I made an appointment with her for Friday at 10:00am but I waited until I called her and she promised me another one lateron Friday which never took place .I then called her again she made another appointment for Saturday at 2pm which never took place again. I wasted my time and money. What's worse is that most of the houses that are advertised by homenet are sold long time or offer pending. I think this is unfair to us who are looking for houses, we are wasting our time ,money and energy.
