Unbelievably disgusting service. Not worth giving even one star. Had a viewing arranged yesterday in Manchester, M22, called them after waiting for half an hour and I was told someone will call me back waited for another half an hour and no one bothered to turn up or call back.
First impressions count and this has left me feeling doubtful about this estate agent. I will never contact them again. So unprofessional, very quick in sending emails and text messages.
