The survey and installation were carried out efficiently but the start date was changed and the scaffolding remained in place for about 2 weeks after installation was completed. Since that time I have sent emails to the company asking a couple of questions. These were ignored initially but I have now had a telephone call responding to one of the questions. I am still waiting for an engineer to contact me with regard to the second question. In view of this I would suggest that the company consider the appointment of a dedicated customer services person to deal with after sales enquiries.
