Purple Bricks adverts properties on sites such as Zoopla, Rightmove, etc. They provide a telephone number and when you call, an automated voice asks to register at their website for a viewing, which I did. Then, I had a confirmed viewing date. I turned up at the property even 10 min earlier but no agent turned up. As everything automated, you can't get hold of them because their phone is purely automated voice record. One neighbour of the property said, a few other people had the same problem. Basically, they cancel your viewing whenever they wish to, without even letting you know! Is this professional and ethical ?
