Useless in every respect. When we first approached them they sent a (seemingly) very nice chap around called Andrew who charmed us and made a lot of promises about their excellent level of service. Once the contract was signed, he promptly disappeared and since then we've been forced to deal with a bunch of incompetents who don't answer emails, don't offer even a basic level of customer service and generally don't give a toss. Plus they threw in a bunch of hidden costs that were only mentioned in tiny print in the deliberately long and dense legalese contract. Their policy is just to get you on the books and then to screw you for all they can get. Avoid at all costs!
What agent could do to change your mind?
Answered my emails, acted like decent human beings.
