I read a lot of reviews about Asko-group, and decided to share my information.
Asko-group is not a manufacturer, they are resellers. Moreover, manufacturers of metal-plastic windows no longer want to work with them.
So: Asko-group takes an advance payment from customers of 70-80% of the total order amount, which should be enough to settle with the manufacturer. They place an order for production, ship and install windows (this is a separate topic), but they still do not pay off the manufacturers. When asked: "when will the money come from you?", they begin to be shamelessly rude. As a result, manufacturers of plastic windows are leaving them, for which Asko-group has a ready-made solution - they are constantly looking for new manufacturers of metal-plastic windows with very attractive offers!
As they say: "you won't cheat, you won't sell!"
