We used a local estate agent (as sellers) and we were left feeling unhappy with their behaviour and communication.
So I left a bad review on Google, just setting out what happened and my feelings about it. Now I see when I look them up on Google maps they are listed as 'off line' and you can't read any of their reviews! The other reviews were OK, but mine being the most recent was at the top. A bit worried now, can they do anything to me? I only wrote the truth to warn other potential customers.
