This company is a joke they fitted the my front door and after 4 months I cannot close the door they sent staff to change the lock but they discovered the door is bulky and needs to be replaced with a brand new door. I've sent over 6 emails to different managers and nobody has responded to me and during the 4 months. I have called every week and nobody can give me an answer. I Spent £4000 on this product, I don't want you to order from them and be disappointed, cheated and scammed and come in contact with the same problem, they gave me 20 years guarantee and that's a lie, my door is only 8 months old and i already have such a big problem with it. Must be very bad quality to have such a big problem only after 8 months.
