This company were a disaster. Complete rip off and I ended up getting trading standards involved. The company went to ground and avoided trading standards with false information and denial of operating from their address.
This company are still on the Quotatis web site despite Quotatis being involved with my complaint. So all in all best avoid a company who knowingly send cowboys round to your house.
Many thanks for your comments to confirm that the contractors account has been closed for a period of time and Quotatis are not promoting this company.
