Air-conditioning from Whirlpool is defective for the second time in a short time. If you want to make an appointment for repair, you will receive a date about 3 weeks in advance. You must then be at home from 8 a.m. to 8 p.m. The technician then called with an anonymous number that he would be there in 10 minutes. The engineer then says that he cannot get behind the barrier to park (which I could not have opened at all), so I have to make a new appointment. He never rang the bell and did not provide any information to call back. Then I called customer service, which indicated that they can do nothing and can only schedule a new appointment again in 3 weeks, in exactly the same way, with another time period from 8 a.m. Worthless service!
