We chose a company through rated people to build a sunroom. Home Restore Scotland gave us a quote for £32000 which we accepted. We paid a deposit of £6200 on May 4th. We have had to chase them all the time. So far we have received architectural drawings and an engineers report. The certificate of design has been granted by our local council over two months ago. The company will not answer our telephone calls or return emails. What do we do?
