When will the machine be fixed?

M: Oh, it’s too cold in here. I thought the heater was going to be fixed last weekend. What happened?
W: It was supposed to be fixed, but it turned out(66)the repairperson was unavailable all of a sudden. I heard he was involved in a minor car accident while coming to our office. So now(65)we have to wait until the day after tomorrow for it to be fixed.
M: I hope we can hang on till then. It’s so hard to work in the office under these circumstances. Have you talked to the manager about this problem?
W: I haven’t had a chance to talk to him yet.(67)I hope our maintenance department will be able to install a couple of portable heaters until the central heating system is actually working again.
