I had lots of issues with SmoothMove when buying my house. I won't go into lots of detail, but I was constantly having to chase, and they promised callback after callback, even at specific times, and never got back to me. Full of empty promises. I am now looking to sell, and thought I'd give them another chance as this was 5 years ago. I requested a valuation over a week ago, and they still haven't replied to an email or phone call. I made the request through their website. Seems some things never change. Unless you want to chase an estate agent daily where it seems like they get a buzz out of not replying, I'd stay well clear.
