Our air conditioning in the maids room and in the bedroom is not working properly. We have 30 degrees in the room. Technicians were here two days ago to report the damage and give me a quotation. I had to pay the invoice for this to ServeU in advance. This happened yesterday. I was assured that the damage will be repaired today.
Since no one has come until now (5pm), I called. Now I was told that the damage can only be repaired on Sunday.
I have experienced a lot of incompetent management in my life, but this is beyond the scope. I understand that now that the temperatures are rising, there is a lot to do. I don't blame the technicians at all. But the management should consider whether this is the right way to look after customers. Absolutely unprofessional.
Unfortunately I must give one star. But I mean zero out of five stars !
