Aluminium windows from the s****yard

Don't dare go near these guys it's thee worst aluminium windows I've seen in my life. Cheap windows, window hinges skew, window frame you can literally see outside where the frame joins, rubber that holds windows are broken. Only discovered this after the windows were in and plastic was removed a day or 2 later as per the guys instructions. I deeply regret using this people so please do not make the same mistake as me.
