When the windows were first fitted, they were not as the plan showed. The Company kept asking to make appointments for us to advertise their product, several times, then not showing up when appointments were booked. Kept getting our address mixed up with another in our area. Today we have been locked in to our property as back door lock no longer works, told would have to wait several days until it is fixed. Told a manager would contact me as the call handler couldn't process an emergency call out. Company only installs badly and makes false promises, such as their product would cure damp, in the house. No emergency call outs, if product goes wrong. Only had their product for 3 years.
