Bad ... I bought the boiler and air conditioner in the summer, to get the invoice for the air conditioner I had to call 1000 times and it finally arrived at the end of December. In mid-December I then bought two more air conditioners, enticed by the discount on the invoice and today, January 19th, I announced that I no longer want them. But can you wait over a month for two air conditioners? I had asked them to hurry up because I don't have gas yet and they would have been the only source of heat in the house. Let's not talk about the toll-free number, more than once I gave up talking to the administration after waiting over half an hour on the phone.
