In the meantime, we have to stay at home 9 times in half a year because it cannot be solved in one go. I also had to stay at home 2 times for nothing because a part has not arrived. I have had the company on the phone at least 30 times in the last six months and I have to go after it myself every time. Very tiring and especially unnecessary.
