The service works terribly. I ordered the windows on October 24, by December 12th I had not yet received the order and the installation had not been completed. There are always some excuses: there is no car (we cannot bring the order), then we did not order window sills and they lie at every step. There is no question of compensation, I did not order from the factory, and the contractor is not to blame. According to the contract, I paid the first installment of 70%. The deadline is 21 working days. There are no windows, no money. Thanks to WDS! Just a dream!
